Dive suit

The dive suit is a pickup in The Ancient Gods, Part One, the first expansion for Doom Eternal. It is found in the UAC Atlantica Facility and is vital for accessing the underwater building where the Seraphim's body is located.

Tactical analysis
The dive suit allows the player to breathe underwater for as long as their oxygen meter is not empty. The oxygen meter can be refilled by either standing on solid ground or picking up an oxygen tank while underwater.
