Err Niether I ussally stay alive 9-10 times for that map.....
Heres the thing with deathlab.
People in the beginning, they fall.
They bitch and whine (even though they voted for the map)
and they leave....
The remaining humans get through the traps and get to the ammo room.
Of course no one wants to be a zombie so they instantly leave.
If there are zombies who stayed, it wont be much.
Who cares right, after this round, they will vote for deathtime. After 30 mins of that as well,
It's deathlab once again and we're back in the beginning.
Bottom line is, carp is right.
