Eidos Interactive has announced a version of Tomb Raider: Legend will find its way to the Sony PSP upon the game's console debut this spring. According to the press release, the PSP version will be "based largely on the PS2 version of the game", and will include exclusive game modes and Bonus Reward Content. I have to admit, I'm a bit confused by the PS2 comparison, as the PS2, Xbox, Xbox 360 and PC versions are supposed to be the same. Ah well.
In addition to Tomb Raider: Legend, the PSP will also host Tomb Raider: 10th Anniversary. According to Gameshout, TR: 10th Anniversary "is a 'special edition' of the original Tomb Raider released for the PSone and PC way back in 1996."
