The shooter that was, along MotorStorm, one of the most craved titles when PlayStation 3 launched back in November 2006 is getting a sequel.

Insomniac’s second installment for the highly-praised FPS will be revealed in the February 2008 edition of GameInformer, a review which has also offered us a sneak-peek at GearBox’ Borderlands, back in September.

The guys at Insomniac are definitely skipping some nights of sleep since they’ve barely finished working at another PS3 blockbuster, Ratchet&Clank: Future Tools of Destruction. Resistance 2 is their next project, currently in development and slated for a Q4 2008 debut.

According to the details that have transpired in the media, the game will bring huge environments for the multiplayer component, capable of holding no less than 60 players simultaneously. The single player campaign will support co-op play for 2 players, while the online single player campaign will allow for up to 8. GameInformer says that “multiplayer maps are positively huge, with an increased focus on individual battle zones, use of cover, and logical flow of movement, rather than empty haphazard areas where everybody charges for the center of the map.”

Just like in Valve’s Team Fortress 2, Insomniac will introduce classes for the online battles, like the Heavy, the Special Ops or the Medic. New vehicles (including the alien-built Stalker, which will have cloaking abilities, and the Chameleon) and more intense boss-fights are also promised, besides the partial randomized geometry in level spots.

What we know for sure is that the game’s plot has now moved to the US and that Resistance: Fall of Man hero Nathan Hale is back. Insomniac is busy improving the AI, and is considering a technique that will allow the enemy closer to the player to have more sophisticated AI routines than enemies situated further.

The announcement of a sequel is not exactly a surprise, considering the success the first title had. According to VGChartz, Resistance FoM sold more than 2.24 million copies since its debut.
