Tremulous is a great game! The core system is all there, and best of all, it works, and is balanced. Now, polishing it up with the cool stuff will turn it from a good game into a great game.
Humans
Flashlight:
An attachable flashlight that can be equiped to a weapon or construction kit. The flashlight has unlimited power, but only while a reactor is online. There should be some penalty for using the flashlight. Perhaps you appear on the aliens' sensors earlier.
Laser Sight:
Would look cool, i cant imagine it would help at all. Maybe make it an appearence option for players to remove the targeting reticle and replace it with a laser sight.
Aliens
Hive Mind:
This toggle ability expands your radar to include any humans and structures detected by another alien or alien structure. Enemies who are not in you range appear green, and are always overlapped by the ones that are in your range. This will allow people to find the human base if one alien has found it.
Leech:
10% of all damage inflicted on humans is added to your health. (might be cool, might not)
