Welcome to Lunabean's Unofficial 'Splinter Cell: Double Agent' Walkthrough and Strategy Guide
. This guide is written for the Xbox 360
version of the game. It will also help those playing the PC
version of 'Double Agent', with the exception of a few control techniques noted in the introduction. It will take you through the single-player campaign and will teach you how to earn a 100% stealth rating
on each level.
The guide was written based on playing through the game on "Normal" difficulty. However, the goal of the guide is to get you through the game in the stealthiest manner possible, in order to earn a 100% stealth rating. That means that you rarely fire any bullets, nor do you kill or knock out anyone (with a couple exceptions, noted in the guide). Obviously, you can get through the game by shooting and using your 5th Freedom (kill anybody you want). This is fun and the guide will help you if that's how you want to play, but the real skill comes into play when you try not be seen, don't have any guards' bodies found, don't set off any alarms, and generally get in and out without anybody knowing you were there. That's what this walkthrough will teach you how to do. Because of this, the walkthrough will greatly help anyone trying to get through the game on "Hard" and "Very Hard" levels (particularly because you aren't given any SC-20K lethal ammo on the harder levels).
Differences between the levels have more to do with guard sensitivities and lack of ammo than anything else. Guards in the hardest difficulty seem to be sporting the "Whisper 2000", as the slightest movement can be heard by them. Also, guards are much harder to kill in higher difficulties, while a single shot can often take you down. For these reasons, it's best to play through on "Normal" before even attempting the "Hard" level.
Gameplay Tips and FAQs
Most of the game's basics and tactics are explained as you come to them in the game. However, we have included the below section for quick reference.
Pattern of the Enemies
This guide is written with the goal of getting you through the game with a 100% stealth rating on each level. This is tricky as movements of enemies change between games. In general, enemies stay in the same area. However, if you make the slightest noise, they can completely switch patterns on you. What's more, 'Splinter Cell 4' provides an interesting AI element. The AI isn't necessarily smart (enemies still can't see you in the shadows, no matter how close to them you are), however, it will also cause enemies to change patterns if you continue to play through the game in the same way. So, with that being said, we have provided a guide that attempts to get you past enemies based on their most common movements. If movements are slightly different in your game, work with it. If you're going to earn 100% stealth, you're going to have to know how to get past enemies on your own.
Remain in shadows
Pay attention to the threat indicator light attached to your back. Yellow means you can be seen, green means you are completely protected by shadow (although enemies can still hear you if you move fast), and red means you have been spotted. Being spotted does not necessarily mean an alert has gone out, but it is likely.
Also, be sure to listen to the game. If you suddenly hear a suspenseful musical note, it's likely you have stirred interest in a nearby enemy. Get out of the way, because he's coming for you!
A good way to get an enemy out of your path is to make some noise. If you press down on your "D-pad" you make Sam whistle. This will draw an enemy toward you, allowing you to take another path to get past him, or take him out. Another option is to use the Ultrasonic Emitter, which is earned after successfully completing the "no alerts" objective in Ellsworth Penitentiary. This is good to use if a guard is coming at you. Simply aim it away from you and shoot. The guard will turn around to find the source of the sound.
Back to Wall
You can place your back flat against a wall by clicking down on the left control stick. While you have your back pressed against a wall you can move left or right. This is a good way to sneak past guards.
Dealing with Pipes
Constantly keep a lookout for pipes, both vertical and horizontal, that you can climb. While on a horizontal pipe you can pull your legs up (hit "A") to be more stealthy, you can hang down from your legs and grab enemies below , you can drop down onto enemies, and you can pull out your gun and fire while hanging.
When you get close to an object that needs an action performed on it, an action icon will appear in the middle of the screen. If you tap "A", that action will be immediately selected. However, sometimes you will get more than one option, which you can find by scrolling through the options while holding down "A". This way you can choose, "Open door stealth," as opposed to "Open door". Speaking of things you can do from the interact menu...
When you approach doors you'll have several options. You can look under the door with your Optic Cable to see if any enemies are nearby, you can open door, you can close door behind you, and you can Open Door Stealth. If you choose this option you can slowly open the door using your control stick. Another option that is new to Chaos Theory is "Bash Door". If you choose this option you will kick the door open meaning if anybody is on the other side of the door, he'll be knocked out. Keep in mind, though, that guards can do this to you, too.
Another Interact item is Lock Picking. Picking locks is fairly easy. Simply move your control stick until you feel the controller vibrate. Keep it in that position until you hear a click and you see the pin move up. Usually locks have 2-5 pins that you need to pick depending on how secure the lock is.
To crack a safe you must get each of the disc tumblers in the right position. You'll know they are in the right position when you feel a vibration and/or when the disc lights up. Like real combination locks, you must change directions when spinning this lock. So, begin by spinning the lock clockwise (control stick or directional keys). Eventually the disc closest to you will begin spinning. When it does, wait for it to turn green, then stop. Next, spin the discs counterclockwise. Be very careful this time, as, if you miss the sweet spot, the entire lock will reset. When the second disc is set, spin clockwise again to successfully crack the safe.
Another interact item is "Use Computer". This works for many desktops, laptops, and servers in the game. Often, objectives are found on computers. Sometimes a computer will have security access where you'll need to hack it.
Hacking is a fairly easy process. The computer is trying to solve the code itself, it just needs you to help it along. There are four columns of numbers. Watch as some of the numbers in each of the columns lock on to a number and stops searching. The locked upon numbers will be the same per column. When you spot one, move the cursor over the locked on number and select it with "A". This is the number for that column. Move over to the next column and repeat. Repeat two more times to solve the code.
OCP (Optically Channeled Potentiator)
Your Pistol has a neat and functional feature called the OCP. You use this with your "Secondary Fire Button" (left-trigger) when your Pistol is equipped. The OCP is used to jam items/objects such as cameras, lights, and generators. It only works for a limited amount of time. If you use your OCP and miss the target, a red light will appear on your Pistol. If you are successful with your OCP usage, the light will glow green.
Mantling, Climbing Ledges
If you are having trouble climbing up ledges, make sure you are pressing forward on the control stick and pressing your "A" button when attempting to climb.
Lethal vs. Non-Lethal
With the exception of one level and a few special cases, you can make it through this game without killing anyone. What's more, you can make it through this game without even knocking anyone out (again, with few exceptions). In fact, that is the goal if you plan on earning 100% stealth. However, for clarity here is a bit about non-lethal KOs (lethal involve bullets).
If you are sneaking up behind guards, crouch (with "B") and slowly move behind them. When you get the interaction icon, tap "A" to grab them. From here, you can either knock them out (sleeper hold) using your "Secondary Fire Button" (L-trigger) or you can kill them using the "Primary Fire Button" (R-trigger). Your SC-20K is also quite useful for non-lethal kills. You have at your disposal Sticky Shockers, Airfoil Rounds, Gas Grenades, and Sticky Cameras, all of which will take out out guards without hurting them.
Throughout this guide I rarely recommend you fire any bullets or knock out any guards, although you are definitely free to do so if you want, you just won't get your 100% stealth rating.
100% Stealth Rating
To get a 100% stealth rating you can neither kill nor knock enemies out, except for special situations, which are noted in the walkthrough. In the rare situations where you do have to KO or kill someone, you have to hide their bodies in places where they won't be found. What's more, you cannot be identified as an intruder, nor can you set off any alarms. This guide was written to get you a 100% stealth rating on each level.
Although I don't tell you specifically to hide each and every body you take out in the game, as a general rule, be sure to hide any bodies in dark areas or out of the main path of any potential guards.
Picking Up Objects
Throughout the game there are many items that you can pick up and throw to distract guards. Usually it is an empty soda can or some such piece of trash. If you do pick up an item, you can simply drop it again by pressing your "Primary Fire Button" (R-trigger). If you want to actually throw the item, treat it as a weapon you want to fire. Simply "Aim" and "Fire" to throw it.
You can save at any time by simply going into your "Start" menu and selecting "Save".
For the purpose of following this guide, move through the game at a steady pace. Doing so will, most likely, ensure that guards are in the positions that are specifically referred to in the guide. If you go too slow or too fast you may find different patterns to the guards. This isn't a problem as, more often than not, the guards will return to their normal paths. However, keep in mind that my timing may be different from your timing. Don't let this frustrate you. Simply read the entire section on which you are stuck, and you will soon observe guard patterns that are noted in the guide. It should also be noted that guards who hear movement or shots can change their pattern of movement completely.
Switching your SC-20K Attachment
Your SC-20K has many different attachment options, and you will get more as you complete starred objectives. These attachments include the Sticky Shocker (easily knocks out any guard in one shot), the Airfoil Ring (also knocks out guards, but requires more precision), the Gas Grenade (gasses those not wearing masks), and the Sticky Camera (used primarily to view and gas guards). Launch these devices by using your "Secondary Fire" button (pull the left trigger).
For controls, go to the Solo Menu and select "Options". Here you can invert your controls (I always invert Up/Down), and you can check out the "Controller Layout". Since this guide is written for the Xbox 360 and PC, I will primarily be referring to buttons based on their actions as defined in this Controller Layout menu.
I'd suggest going through "Training", although it's not necessary (quick tutorial walkthrough below). Once you have your controls down and have completed both tutorial courses (or not, it's all up to you) choose "New Game" > "Normal".
NSA: Training - Test Course A
Exit through North Door
Begin by simply moving toward the open doorway. From here you'll be taken into a room of light and shadow. Note the threat indicator attached to your belt. It's green, meaning you are protected by darkness (yellow means you are not). Move toward the picture while avoiding the moving spotlights.
Next, you'll find yourself in a room with lasers and cameras. Move straight ahead to the pile. Climb it to the top of the half wall. Stand up from your crouched position by hitting the "Posture/Drop" button ("B"), then, stand beneath the horizontal bar. Hit "Jump" ("Y") and you'll automatically grab onto the bar. Hit "Jump" again to pull your legs up.
Move along the bar until you find yourself above the computer. At this point a square icon will appear on your screen. This is the "Interaction" icon. Don't worry about it at this point. Instead, Hold down the "Action" ("A") button and you'll get a "Use Wench" option (if there were more options, or if you wanted to cancel out, scroll left or right then release the "Action" button when on the selection of your choice). In this case, release the "Use Wench" button to select that option. You will find yourself dangling upside down.
If you want to Remain Undetected
(a Secondary Objective), then you're going to have to do something about the cameras. Pull out your 5-7 SC Pistol (this will be the default weapon you are armed with when you hit the "X" button). The secondary function of the Pistol is that of the OCP, which disrupts electronic devices. Take aim at either of the two cameras (you should be able to rotate around at 360 degrees once you are hanging upside down). When you have a camera in the Pistol's sight, hit the "Secondary Fire" button (pull the L-trigger). You'll note a red or green light on the Pistol. Green means you have been successful and the camera has been affected. Red means you have failed. Reposition your aim and try again (although, you'll have to wait for the green bar to refill before you can try again).
When the first camera is out, quickly spin around and hit the next camera. Again, you'll have to wait for the green bar to refill before you can activate the Pistol's OCP again. When both cameras have been deactivated (temporarily, so move fast) quickly hit your "Unequip" button. You'll be hanging above the photo, as you were before. Quickly lower yourself down (if playing on a console, this is done with the control stick). At the bottom you'll automatically break from the wire. If you were positioned correctly, you will not fall into any lasers. You should now have a "Retrieve Picture"
interaction icon. Hit "Action" ("A") to do so.
, I made you do this the hard way, as it's vital that you learn how to use the Pistol's OCP early on, as skilled use of the OCP is key to making it through the game with 100% Stealth (and, no one said being a Splinter Cell was going to be easy). However, if you have trouble timing both cameras and safely dropping down, continue along the bar to the room with the computer (upon reaching the end of the pole, drop your legs so you can slide down). Once you reach the computer you'll get the "Use Computer" interaction prompt. Hit and release the "Action" button to do just this. You'll be given a "Disable the cameras" option. Select it, and you'll be asked to hack the computer.
Hacking is a fairly easy process. The computer is trying to solve the code itself, it just needs you to help it along. There are four columns of numbers. Watch as some of the numbers in each of the columns lock on to a number and stops searching. The locked upon numbers will be the same per column. When this happens, move the cursor over the locked on number and select it. This is the number for that column. Move over to the next column and repeat. Repeat two more times to solve the code.
When the cameras have been hacked, climb back up the pole, then use the wench and lower yourself down to the picture (as described above).***
At this point the room will clear out. Run up the stairs and move through the door.
Stealth Score: 100%
NSA: Training - Test Course B
Retrieve information from hostage
You begin this level atop a high pillar. Quickly look around and note the four rooms. The guard will enter the room at the top of the screen and to the left. Note the two doors to this room. One is on the right side (the door the guard uses) and the other is at the bottom of the room. Quickly fall off the pillar by moving to the bottom of the screen. You will land in a crouch. Stay crouched and run to the door at the bottom of the room where the guard is. Go to the left side of the door and use the "Back to Wall" button (most likely a click of the left control stick). Wait until the guard exits.
As the guard moves across the room to the next door, move yourself away from the wall (press "Back to Wall" button again) then slowly move behind him (if you move fast, he'll hear you). When you get close enough to the guard an Interaction icon will appear, giving you the option to "Grab". Press "Action" ("A"), then release to grab the guard. Once in this position, you have two options: Kill or Knock Out. To get the best score possible, you can't kill. However, this is one of the few times when you can Knock Out. So, use your secondary fire button (L-trigger) and knock him out. You may care to note here that you didn't have to hit "Action" before actually knocking the guard out. You could have, simply, hit the knock out button when you got close enough to him. However, hitting that "Action" button is a very good habit to get into.
Now that the first guard is out of the picture, you must exit the area. Assuming you are still in the hall between the two rooms, run toward the white pillar, hang a right, and approach the double doors at the end. Open one and move through it.
Here you will find two guards protecting the hostage. One is at the base of the stairs, the other is in the heart of the maze. Quickly arm your weapon, the SC-20K Rifle. Once it is in your hands, press and hold the "Weapon Select/Inventory" (RB) button. While you hold the button down, you'll see a few options for the SC-20K's secondary fire option (the up and down options). Scroll up until you have the Sticky Shocker selected, then release the button. The Sticky Shocker is now loaded into your secondary fire compartment.
Move down the stairs and head right. Chances are the guard went down the second hall to your left. Slowly approach the hall (so he doesn't hear you), then turn the corner and aim at the unsuspecting guard. Pull your secondary fire button (L-trigger) and release the Sticky Shocker. The guard will be knocked out.
The easiest way to hit the second guard is to return to the stairs, then take aim at him from a distance. You only have two Sticky Shockers. So, if you happen to miss the guard, go into your ammo inventory and select the Airfoil Ring. The Airfoil ring does essentially the same thing as the Sticky Shocker, but it has to be used on an enemy's head. For this reason, you'll have to get closer to the guard. Don't worry about him seeing you from this position, so study how to reach him in the maze, and sneak up to him.
When both guards are down, make your way to the hostage. When you reach her, you'll get a "Release Hostage" option. Take it and move up the stairs.
Stealth Score: 100%
