Would it be at all possible to add a feature (maybe optional CVAR) that places bloodsplats on a creature set to bleed? This would be a cool way to see if you're actually hurting something, and if so, how badly. Don't let the decal be drawn on cyan (or index #257 if you're going to be particular) and you've got a cool effect.
Rotations would kind of spoil the effect, as the engine doesn't know how to place the decal in a new postition, but it would still be awesome to see an imp get more bloody every time you shoot it. JDoom does this, to a degree, too.
