Insomniac Games officially announced Resistance 3 and Ratchet and Clank: All 4 One during Sony's GamesCom press conference. Ratchet and Clank: All 4 One will be a cooperative four-player game featuring four characters from the previous Ratchet and Clank games; Ratchet, Clank, Dr. Nefarious and Captain Qwark. The game can be played online as well as offline.
The long rumored but never before officially mentioned Resistance 3 has finally been acknowledged by Insomniac, although little detail was given. What they did say was that since Resistance 2, they have listened to the fan feedback and fine-tuned what they think will become a respected addition to the franchise. The official live action trailer for Resistance 3 can be found here.
Both games will be exclusive to the PS3 and although no official release dates were given, both games are expected to arrive some time in 2011.
