Been playing around with some ideas. Here's a bit of my brain, one for each category of gun. Primary: Arc pistol. Semi-automatic, damage drops off heavily at mid-long range. Some splash damage around target when shots hit. Special: Gravity rifle. Single slug per pull. Slow fire rate, high velocity rounds. Damage drop off at long range. Each round causes concussive shockwaves that push targets hit back and sideways, no damage on AOE. Heavy: Heated chainsaw/Laser sword/Incendiary Impact drill. (They're all going to work the same, take you pick) 1-hit kill. short range only. Slight wind up before strike. Low ammo capacity. Frenzy/adrenaline effect (the lower your ammo, the faster you move) Thoughts?
