It's a closer range weapon than you think. The magnetism makes it devastating at close-mid range. Don't be afraid to be aggressive with it, don't treat it like a Sniper/Spartan Laser. You should be on the front line, but also careful about where you are on the map. It's an easy OHK, but the reload time makes it so you need to be near cover to string together multikills. So don't just go out, guns blazing. You should be on the offense while also playing smart and conservatively.
The mind of the subject will desperately struggle to create memories where none exist... ~~Keep Calm and Chive On~~
