sheepeez’ beam sword idea is good. It should be able to instantly cut/kill anything but would have a super-short range. Technically it should be able to cut tanks treads but not kill the tank, as a tank would be too large to kill. It could cut big bugs’ heads off (instakill), but the player would have to be on the correct side of the bug and would risk get run over by charging bugs. The beam sword could also be made a perk that replaces the pistol.
I’d like to see a powerful projectile weapon that is so powerful it knocks the shooter over (so they have to get up, but they get up faster from this than from actually getting shot). This weapon’s damage would have to be worth the delay between shots.
