Currently taking a break from Wave 8 of Horde solo. Jesus. Ammo runs are the worst. I'm normally alright, holed up in my little base. I'm not great, but I'm alright. But when I run out of ammo, oh god, it's horrible... Also, the rhythmic vibrations that increase in strength which let you know a boomer/grinder/mauler/big fat guy who wants to eat you is approaching your position are pretty disconcerting. (EDIT: Also the way they cough and wheeze if you've injured them as they approach is pretty too)

AK I added you on XBL but it says you have a Silver account, so I dunno if you'd be able to play with us with that. I reckon Dan would be down for a Horde mode too so that's two at least.
