fist idea:
buy psaw + battery pack, and you activate the secondary fire in psaw, a small Lightning Gun, This gun will crackle with lightning as you fry your enemy with pure electricity(like q3).
yes, but, in tremulous, Lightning has slightly less damage than the lgun and the Lightning is very susceptible to overheating.
psaw + Bp - primary fire = cut, secundary = lightning
--
lucis grenades =
Lucis(gpp) is more like a RL, then, like unreal, the secundary fire shots grenades(or energy grenades

), I think more fun.
primary fire: default energy balls.
secundary fre: energy grenades.
holding down the secundary Attack you can loading up to powerful energy grenades before firing. Once released, the grenades fly out, bouncing off solid surfaces and exploding after 3 or so seconds if they do not impact with human/aliens flesh beforehand. Unlike the " Energy Rocket Launcher" aspect of this weapon, the grenade launching Secondary attack does not come with any built-in tricks, though with the ability to bounce around corners and swarm confined spaces, grenades certainly have their uses.

and, some zoom for rifle, lgun, prifle and blaster : )
nice ideas?

more ideas:
turrets and hiver(or )Trappers - can reach targets at long distance.
turrets_ have some spread, but, can shoot targets at long distance(like TFC/TF2, hl/hl2 turrets or natural selection, besides being useful to support, would be more fun.
missiles turret, simple, a turret that fires energy missiles, does not cause much damage, but can reach targets at long distance(and good to kill small aliens).
hives - can attack several targets at once(like 3 humans)or Trappers cause a small damage and have more range.
for close range, use Teslas or Acid Tubes.
the possibility of listening to music during the game, or a soundtrack terror style f.e.a.r or avp : )
