Boss Fight: The Keeper

The Keeper appears after a long speech and positions himself on an invulnerable platform. You must first defeat waves of enemies: mutants, harvesters, and hunters. Plasma leech gun stations and health spores are available.

Once the centurion falls, The Keeper will descend. He attacks by firing two projectiles. Stay at a distance to avoid them, dodge when necessary, and attack him with any weapons, especially explosives. Avoid the circulating energy beams in the arena. Continue attacking until he is defeated.

After defeating The Keeper, a portal opens beneath you, leading to a new area with lesser keepers.

Tips
  • The health upgrade before the first enemy wave makes the fight easier.
  • The Keeper is surprisingly easy for one of the final bosses.
  • Explosives are effective against The Keeper.
  • Dodge projectiles by moving to the side.
