It’s a neat gimmick, would love to see it explored more. I have some ideas, for fun.
Maybe a launcher that shoots a big mine that lands on the ground and flies to enemies that approach?
How about a pistol that shoots mini rockets?
A laser AR would be great with the homing mechanic.
How about a laser AR that splits into multiple beams, hitting every enemy that gets hit with the tracker?
A launcher with reduced ammo consumption that shoots mini rockets would also be cool.
A pistol that shoots kunai? Could be given by Zer0, and have the kunai inflict a random element and a ‘0’ tag on the enemy.
Maybe a reverse Atlas gun that shoots Tracker bullets and smart grenades XD
