There not referring to mods in the usual sense where you can have god mode and Infinite ammo and what not. It refers to being able create custom maps from the software. So now the community can keep the maps coming. It's pretty big on World At War, and there some pretty cool maps too. you should check em out. I'm sorry for bumping this BS thread too guys.
Black Ops 2 won't get mod tools because they would lose out on DLC sales on PC.
I bet they Sell more dlc bcus you need it for the modded maps. In waw you are not able to play mods and maps with dlc items in there. Only prototype style maps work when you not patched the game with the dlc.
