Sony is holding a
Double XP weekend for
Killzone 2 this weekend to celebrate the launch of the new mappack and patch for the game. The new map pack includes two new multiplayer maps for the game (see video below) but also allows you to use the bolt gun and the flamethrower in the multiplayer portion of the game.
It will be interesting to see when and if we get any more DLC for the game as Guerrilla games is
stepping away from the franchise to gain perspective and to figure out what to do next. Hopefully they continue to have some folks work on new maps while they start a new project but I guess we'll see what happens.
