Beat Marlo by waiting for him to turn before attacking in stage one, then bait his charge into a wall and time the movable arena object over him in stage two until you can finish him off. This hellraiser revival marlowe boss fight guide covers the two-stage final encounter in Clive Barker's Hellraiser: Revival. For other encounters, use the Hellraiser Revival bosses guide.
How do you damage Marlo in the first stage?
Wait for Marlo to turn so you can attack past his covering position.

- Watch his covering position. At first, this can look like a fight where you just need to keep shooting. Read his turn as your opening instead. Check that he has turned and your attack can reach beyond the area he is covering.
- Attack during that opening. Firing while he is covering himself prolonged one player's attempt. If your shots keep failing to connect, wait for the next turn rather than spending more ammo on the same covered angle.
- Prepare for another stage. The Marlo two stage fight continues beyond this opening phase. Once you are working with his charges and the arena object, switch to the positioning sequence below.
How do you beat Marlo's charge and wall fight?
Bait Marlo into charging, let him hit the wall, then use the movable arena object when he is underneath it.

- Lure him into a charge. Make drawing that charge your immediate goal. Watch for him committing to the charge before moving on to the wall part of the sequence.

- Let the charge reach the wall. The check here is the collision itself. Keep your movement clear of walls and debris; one player became stuck against them while trying to get away.

- Check his position before using the object. He needs to be underneath it when you time the action. Moving the object alone does not mean you landed the hit. Confirm that it catches Marlo; if it misses, set up another charge and check his position again.
Don't rush the arena object just because you've drawn a charge. One player repeatedly missed while unsure whether Marlo was underneath it. Waiting for the right position is the steadier choice than repeating the same mistimed action.
Reloading and grabbing supplies can also make this phase awkward. One player reported being unable to run while reloading and found the pickup animations slow. Give yourself room before doing either, rather than trying to squeeze them in while struggling to escape him.
How do you finish the Marlo final boss fight?
Repeat the charge, wall and object sequence until the finishing opportunity appears, then take it.

The finishing opportunity is your cue to act. Keep working toward it even if the fight has dragged on; one player ran out of ammo before reaching the finish. That makes waiting for useful openings and checking the object's position especially valuable.
One player died in the second stage and had to repeat earlier parts of the encounter. Treat staying alive as a priority, especially around slow reloads, pickups and debris.
Finishing the encounter led to the Go to hell achievement in that player's run. Next, head to Hellraiser Revival endings for the ending guide. Use the Hellraiser Revival walkthrough to return to the wider route, or Hellraiser Revival characters for the cast around this confrontation.
