I know it's undoomish, but we do have a few in-game already. (Spear, Adv RL, Adv Pistol (AoM Challenge))
And since we have these new traits, I think it gives us a lot of opportunity.
Examples:
The Texas Chainsaw
More damage than a standard chainsaw, faster attack speed (made of super-light, space-age materials)
Ebony & Ivory
Pair of unique pistols, faster attack speed, extra damage (but only when both are used in dualgunner)*
Plasteel Boots with cheap plastic wings
Reduces movement time, increases dodge chance (I think boots have been ignored so far, do they only protect from acid/lava?)
Boomstick
Unique combat shotgun, rediculous capacity, slower firing time
I can probably think of more, if anybody thinks this is a good idea.
*Is this even code-able?
