You built in a spam protection right? I wouldn't do a huge smoke, maybe a small flare or something. Smaller than the incendiary, maybe something close to the smoke on Live_Jump. It wouldn't provide much cover but it would provide a visual cue. It doesn't even have to be smoke either. We could make a real flare. Small bright light, faint smoke. Soldiers do use those to mark things since they're easy to throw. It could be somewhat realistic.
I already have a really good sound for one from AA3: S-mAAp_Pack_6.Pipeline.fire_extinguisher
I'd almost bet that the code is easily copy-pasted in AA. Shouldn't be too hard to spawn an emitter. The question is, will it just float or would a spawned item fall if it has karma? I wouldn't like to rely on it for Mac & Linux but I could always make a KActor for the physics mod.
