As you may have noticed, Sony is re-releasingĀ a good amount of their exclusive franchise games in the form of :collections”. Previous collection include God of War, Ratchet and Clank, and InFAMOUS.
Sony has just announced that a fourth collection is to be released, the Killzone trilogy. This will include Killzone, Killzone 2, and Killzone 3 as well as some other goodies. Killzone will be remastered in HD (720p) and will have full trophy support. The other two are already HD games, so no makeover was necessary but you will be gaining all the multiplayer map packs. They will be included in the game, along with the three full games, for the price of $39.99
You can expect to see this collection hit stores on October 23, 2012.
