Is it possible to beat the sequence mode co-op, and if so can you give me some strategies (the later levels really fuck us over)?

I assume you still get the achievement... or else it isn't worth it.

You don't get it, you play for the hell of getting to the end. I just wanna know if it's even possible.

No, they made an impossible game mode just to piss people off...

Horde mode looks cool. Didn't know where else to say this.
