"Makes your second projectile fire backwards."
Back Gun is a weapon attachment which causes your second projectile of your spread weapon to fire backwards. This attachment may be useful in the beginning, but quickly becomes obsolete, as even it's upgraded versions start to struggle in the later levels. Missiles will be a better defense against enemies behind you as they will target the nearest enemy.
Drop Location Edit
It is a drop from Preemptive Strike, Quick Encounter and First Encounter as a guaranteed drop from the Boss of each level.
Combinations and Upgrades Edit
It upgrades to it's adjusted version and it's improved version. Adjusted, Improved and Mod-Attachments may be unlocked through using them.
