: Some of you may have already seen this one, but I didn't post the link here:
We could make a drinking game out of that ... take a drink every time one of you falls in the drink (slime).
I figured this level would cause you some grief. It's very easy to get knocked off the platforms in the slime filled area by compiler bolts (though they didn't seem to have as much punch as I remember). The dropping walls trap with the enforcers in the first room is nasty, and the ambush trap in the hallway right after that is near certain death in solo mode.
I think the missing enemies were in the southwest corner of the map, which is the "normal" way to approach the secrets (you get out of the slime quicker that way). They teleport in when you approach the elevator.
