Man, i'm glad I made all those friends I didn't care about now, they really help filling out Horde games.
I mean, i'm not even saying that Gears gameplay is the best ever made, but the brutality and desperation of horde mode makes it all worthwhile.
It's a game that needs the kind of friends who, having failed wave 39 on hardcore 8 times straight will still be right there going '**** YEAH, LETS DO THIS' then get murdered again while screaming at each other. It's not for everyone, but there's no need to go bitter all over it.
