Sentinel Beam (Halo 3)
From MLGWiki
The sentinel beam is a energy weapon that fires a single coherent beam that exists while the trigger is depressed, or the weapon overheats. underpowered and ineffective in Halo 2, the sentinel beam has recieved a more-than-modest boost to its damage dealing capability in Halo 3. While still ignored largely in they competitive community, it sees limited use in online play to embarrass players that are unskilled enough to be fragged by the Sentinel Beam.
