This game ended up being HvHvZ (Humans vs Humans vs Zombies) - I was on the "Rogue" team of humans who was competing against the "Military" team. I decided we needed pickups and shotguns and to get drunk, but nobody had a pickup.

In the end they had to call the final mission (last stand) due to a standoff of sorts, but I hereby declare Team Rogue as the winner. (Somewhat reasonable, as we only lost 3 or so of our crew, we held together really well.)
