T4R
My ideas:
-Parachute
-Cryo Grenade (freezes enemy for 2 seconds)
-Gravity Grenade (same effects as the grav rocket)
-Rail Sniper (shoots electric bolts, and is a 1 hit kill)
-Gauss Pistol (one shot)
-Firebolt Rifle (like the flamethrower, but isnt heavy, and shoots bolts of fire)
-Sonic Wave Cannon (shoots circular sonic waves. Reticle like RL but is automatic and 3 direct hits causes a sonic boom similar to supercombine)
-Gravity Rocket (does no damage, but impact sends players and objects flying)
