Just go with the latest map verision. Also, I would DEFINITELY be up for this. I've been wanting to play this map so long. Regarding the teams a 3v3 / 4v4 would be best. Maybe even a 5v5, but I doubt we'll get that many people unfortunately.
Perhaps we could also try a couple other Vechs maps, Legendary is incredibly fucking hard, ALL his maps are incredibly fucking hard if he says they are. And Legendary works fine in SMP.
