I think they're playing again later, and I'll play later today after I wake up. If we're doing something, somebody on my steam friends list let me know (Goat, Bob, or Neophyte basically)
also i gotta ask: what's the go with getting the unlockable weapons? i want em.
You can get the unlockable weapons by unlocking the milestone achievements through playing, grinding an achievement server, or using the achievement locker program. So far only medic, pyro, and heavy have their weapons. No word on the next class that will be updated.
