Between the skill-versus-cunning PVP bouts of BATTLEMODE and the heightened challenge of Master Levels, there’s no shortage of ways to test your slaying skills in DOOM Eternal.

Want to crank up the action for both thrills and rewards during the Campaign? Look no further than DOOM Eternal’s Slayer Gates!

Strategically placed across the map, Slayer Gates are optional challenges that unlock by locating the matching Key in that level. Entering a Gate transports players to an arena brimming with an onslaught of vicious demons. Defeat them all and you’ll earn a serious upgrade to your arsenal!
