John Connor may not be a superhuman force that can take out swarms of enemies alone like a Dynasty Warrior, but he's the leader of humanity's last stand against the purge of the machines. It's for that reason that the machines want him dead very, very badly. Watch this new trailer for Terminator: Salvation(PS3, Xbox 360) and you'll get a clearer picture of why John is such a threat to the terminators, that and you'll see some co-op for the upcoming game.
It's all about the teamwork! The resistance has to pull out all the stops to take the fight back to the machines. There's gonna be a lot of teamwork to go around in the game, and you have to keep at if you don't want your skeleton decorating the battlefield. GRIN seems to have done a great job with this one, so let's hope we get concrete details soon.
