Have anyone thought about that this might affect the gameplay in a negative way, think about it, tremulous is a fast- paced game, all about dodging, tactics and reflexes. how do you think it would be if it was a wussy- scare- fest? lesser tactics, lesser skills, dodging and all, more luck- based..
you can hide well enough as it is, from humans, at last, and the flashlight wont fix this at the least , for the human's part.
rather implement a cloaking pack, simply removeing humans from an aliens sense of smell or whatever.
what i have thought about that would be cool, is another tracking system for aliens, instead of the radar, aliens could "smell" a humans trail, alas, he could see a faint glowing trail where a human had set his feet for a short while afterwards..
