#20 - So much time spent on this game...I even managed to talk my wife into playing the campaign in co-op, but then almost toward the end a glitch wiped out our progress...so <I never bothered to play again. The story is silly anyway, a B-movie on Syfy channel, who cares what really happened.
Don't really care for multiplayer either, just a bunch of people running around covers shotgunning each other, gets boring after 5 matches...
But I cannot remember how many hundreds of hours I've spent playing Horde, either by myself or with others. No wonder numerous games copy/pasted it for their co-op experience. Simply because of Horde, this game deserves to be ranked. Without it, no reason to play it. That's why I never bothered to play part 1 at all, and part 3's Horde mode was much less addictive, too many changes...
