Gauss cannon

The gauss cannon is a new "power weapon" found in Doom's 2016 reboot  which was first publicly displayed at  2015 as a multiplayer-only weapon and officially referenced by id Software's announcement of the then-upcoming closed alpha test the following October.

The gauss cannon is specifically designed as a counter to the demon rune relic, with limited ammunition which cannot be replenished and the capability of killing players in a single shot. Its alternate fire mode allows other players to be seen through walls via a form of x-ray vision. Like the demon rune, the gauss cannon will periodically respawn during the arena battle gameplay mode.
