I like those last two:
Poison (Cyan) and Silent (White)
For Silent, radar immunity beyond 500 units would make it even more effective (too much so?). Maybe, instead of silent, muted and cloaked (not totally silent, not totally invisible) 25% of normal noise volume and 75% transparent (translucent/semi-opaque as opposed to invisible/transparent altogether). With some slight long-distance radar immunity (around 600 units?). Call the trait Cloaked or Ghost.
Sorry, let me format that idea and submit it properly:
- Ghost ("Cloaked" Avatar) - 25% normal taunt & jump noise volume, translucent playermodel, radar immunity at 666 units.
I also like the delay in Poison before the first damage with Poison. I'm not so sure about the Infection thing. If you have always-on poison, you should be able to infect quite a few of them just by yourself. One griefer on the "infected" Human team, and an hour-long game becomes an unplayable mess, not worth the limited time I have to put into it. Always-On Poison YES; Infect other team NO (or severely nerfed).
Again, I have to repeat: I hope this gets made. This would be a fun Trem mod. Traits vs. Sidearms. Thought of a name yet? I'm torn between Tremulous: the Timorous and Tremulous: the Quavering.

So - 1 evo each for
traits, and 175 creds a piece for
sidearms, then? (Max one per player?)
@techhead: where'd ya go?
