I was thinking since Conduit "2" has "2" ways to fire your gun, that would carry over to Conduit "3" having "3" ways to fire your gun.
It would be nice to have killstreaks in the game as to "unlock" the ability to use the alternate fire. At 3 kill streaks, 1 alternate fire is unlocked and at 5 another one is unlocked. You can customize which one you unlock first and stuff like that. It's like CoD but has that Conduit twist to it.
That could be kind of annoying to scroll through the different fires though. What if you want the TPC launcher to fire normally, but it's firing proximity mines and someone is rushing you? In a run and gun game, the extra bit of time to scroll through the alt fires could be the difference between an epic killstreak and an embarrassing death. (By the way, I think Firefox should recognize killstreak as a word by default).
