This ERASER Build is optimized against Colossues with a Multi-Hit and Weak Point module focus. This works well with this weapon because it has good weak point and multi-hit stats, and with our modules that gets amplified even further.
Obviously, you must hit the weak points for the gun to do well!
Lastly, we also use the Payout module that allows us to shoot for a longer time because it won't consume our rounds for three seconds. To activate this, you must hit a weak point.
