Things have been pretty silent ever since Sony announced Resistance Retribution for the PSP during E3 last year. One of the coolest features of the game that we know of is the ability to connect it to the PS3 and being able to use the DualShock 3 controller to play the game. Infected mode is another cool feature, one that presents a different story to play through as an infected soldier. To get an early look at the game, Amazon has an offer running up to January 12 that includes an early access demo for anyone who pre-orders the full game. Like the recent Killzone offer, this is an Amazon-only thing. So make sure you get the goods from there to claim the demo code. The full game itself comes out in February.
