THQ has released a new trailer for
Red Faction Armageddon, in which the producers describe the history of the franchise first and then show us some of the features of the game as the enemies, the destruction of the system settings and other interesting news with such a good time. The video is commented in English, but it shows several sequences of play and can be interesting even for non-anglophone.
