Oh. My. God. You are my hero. Creator of Meltdown? I loved that mod!
Weapons:
Rocket Launcher (like the Spinfusor)
Grenade Launcher (100% velocity inheritance, slightly more damage than rocket launcher, bounces if not far enough from target, explodes on impact if it hits an enemy)
Chaingun (faster fire rate, 100% accurate when fully cooled)
Sniper Rifle (exactly like the Tribes one, I liked the original version though which was sort of unique)
Classes:
Outrider (light) - 2 regular weapons
Raider (medium) - 3 regular weapons or two specialist weapons and one regular weapon
Sentinel (heavy) - 2 specialist weapons and one regular weapon, sniper rifle isn't available.
Specialist weapons (all have extra ammo):
Rocket Launcher: holding fire causes your rocket to speed up mid-flight
Grenade Launcher: holding fire after you launch it prevents it from exploding, releasing fire causes it to burst out into a bunch of particles that deal significantly less damage per particle, but more damage total, and spread over a large area. Detonating it skillfully can cause all of the particles to hit your target, instantly killing it. This also allowed the grenade to be used as a mine.
Sniper Rifle: completely forgot.
