Humm, Revokers too? I know there is walls you can shoot through with Burrow Beam, and no I won't say what or where, as we don't need more people cheating with it. If you are absolutely need to know person, go find the vides online. But Revokers I hadn't heard of as of yet, interesting. Wonder why this issue is showing up now, and if is kind of the same issue with both weapon.

Could be. I  was on the Singularity map and was killed by a Surge on the other side of the wall with Revokers. 

well revokers kill me most of the time when i see them firing somewhere else, a sort of magical weapon.. but i blame game lag
