First of all, I think this mod might rock when it´s done ( for example, i loved Gloom..except it crashed on me all the time, but nevermind that now). I read in a post a bit further down about a spiker thing with slime or something. And an idea struck my mind: I actually got a picture of a snail creeping from one point to another ( say a corridore, from left wall to right.) smeering, something that glows/glooms (no pun intended, or sumthin=P). This could be just any shader in green or something like that. It would be about 10 cm wide and do maybe 5 in damage each time you step on it. And why would this help? Well, say you put these chalklines o´ slime just before a base entrance, and space it as such that even if you jump over the first one, you´ll hit the second, and so on. This would
a) slow the players down (because they have to jump very very carefully)
b) wound them so they are easier to get a hold of.
The damage could vary maybe.. say green is 5 HP, red is 15, and blue is 20 (and very very rare). I dunno. What´cha think?
