- L5 · The Port, the High-Rises and the Quad Tower
- Chapter
- A5 · Lanshiang by Helicopter and the Quad Tower: the Dinosaur, the Rooftops and the Walkway
- Where
- 5-4 Quad Tower: the elevator shaft and the pedestrian walkway. **Story Intersection** with Ada.
Weak point
The deformed human face; in human form, the head and the finisher
Centaur 2 again, with a new move: a spear stab that drags you in for a tentacle barrage. Also: charge, claw swipe (close), tentacle smash (close to medium) and bone darts (medium to long). Stay at medium or long range and, when he charges, sprint through the gap he leaves between himself and the edge of the walkway to switch ends. Don't shoot during his speech: it's a timed event.
Reward
On to 5-5 Quad Tower Roof (Leon). In Ada Chapter 5 it leads to the ending: the console, Carla's lab and the credits (achievement What's Next?).
In Ada's solo part, don't expect help from the bots: they're across the gap. With Agent in co-op, he probably appears with whoever is left without a partner (Helena in her sniper room), but that's unconfirmed.
Step by step
- Leon, the elevator cable: climb by alternating the triggers. Halfway, drop onto a ledge and snipe him while he fights Ada. Climb again fast: he chases you and Ada shoots him to save you.
- Split: Leon and Ada on the walkway; Helena alone, sniping from a room in the building. Her hits knock him back to human form.
- Loop: beast → human → headshot → finisher. Zombies keep spawning and drop items: check after every shot. The small platform mid-walkway is the best spot for dodging.
- Weapons: shotgun and magnum, keeping a few magnum rounds.
- Finale: when he “dies”, he drags Leon to the edge. Ada must reach him and use the partner button or it's game over. The AI does it on its own; a human Ada has to run the moment his speech starts.
- Ada alone (Ada Chapter 5, before the above): on top of the elevator, hold out and shoot. On the walkway, rifle or crossbow between charges and pipe-bomb arrows until the scene triggers; you can also counter his fired claw.
- Ada in support: shoot Simmons while Leon and Helena climb the cable (any weapon but the shotgun) so he slips back. A human Leon needs that help or he dies.
