This beloved weapon should make a return in Halo 4. It has been remade in Reach in the anniversary playlists, but should be remade a little differently without bloom and as much power.
Instead of bloom, I was thinking that the weapone would be deadly accurate (like the ZB DMR) but when you fire, the reticle moves up on the screen. Whenever you shoot the magnum, it jerks back and the muzzle aims up in the air. This recoil effect should be on the magnum in Halo 4.
