Left 4 Dead project lead Chet Faliszek has said the 360 community is "head and shoulders above the PS3", and that's why the multiplayer-focused Left 4 Dead series isn't on Sony's console.
Speaking to CVG Faliszek said the community aspects of the PC and Xbox platforms "really fit" Left 4 Dead - so it's not coming out on PS3.
"Right now for Left 4 Dead 2 we're looking at PC and 360 because the community aspects really fit the game - it's all about playing with your friends," he said.
