Preparation
Use the final safe area to restock healing and ammunition, then save. Bring a dependable weapon for the boss’s glowing head and a second option that can remove nearby summoned enemies quickly. Leave enough empty space to take the supplies offered before the door.
Fight loop
- Keep a wide movement lane open instead of standing against the arena edge.
- Fire at Slither Prime’s glowing head when the line of sight is clear.
- When it begins to summon other enemies, break off boss damage before they surround you.
- Clear the closest summons, reload during the new space, and move away from incoming attacks.
- Return to the head and repeat until the boss falls.
Target priority
The fight becomes unstable when every threat is allowed to remain active. Shortening a head-damage window to clear a summon is safer than getting trapped mid-reload. Keep circling through open ground; do not trade movement for one last shot.
Return to the boss hub or review the weapon roles.
