Makes a LOT of explosions.
[assuming we're talking about the same thing here]
More specifically, IN THE OLD MAP IIRC didn't it launch explosive barrels like crazy [in a basement room]? ... in the newer one it triggers/deactivates a pair of lasers that adorn one of the staircases to the basement that, when tripped, will cause the user to explode [and those around it, but not those on the staircase... works more like a jihad bomb than C4 in that sense]... the problem with the new one is that it trips not just when people walk through it, but when ragdolls and props do too, so people put stuff there to keep the explosions going over and over and over and over.... *headache*
