Ray Gun Only is a game mode in Call of Duty Online. In it, the player only receives a Ray Gun, similar to how Call of Duty: Advanced Warfare had a MORS only mode. The game mode follows a Team Deathmatch style, with the first team to reach the score limit winning.
In this game, the Ray Gun doesn't have an ammo counter, and instead will overheat if fired too much. Enemies killed will have their bodies instantly vanish as though they were disintegrated.
