Summary: Most people buy this game for the online play. The truth is that Black Ops is a failure for multiplayer use. Lobbies are never synchronized....leaving huge gaps in aiming and target hit markers. Often times you can be killed without ever having actually been in view of the enemy. The spawns are horrible. Enemy players can sit where you will spawn in front of them, allowing them to shoot you without a chance of even getting one step taken.
Summary: This game is not worth its current price. Far less, in fact. Beware its fatal flaw - it will lag painfully on computers and despite many patches from Treyarch and plenty of optimizing methods to increase FPS in multiplayer, the game will still freeze frequently. The single player is palatable for a first time runthrough, but it's far from something you'll keep in your long-term memory.
