Tyrant room: (Rebecca and Billy) or (Rebecca)

After a cutscene, you will face the Tyrant. Ignore the nearby door for now.

Co-op (Rebecca and Billy): Let Billy use his magnum ammo. You should use your magnum as well. Retreat if the Tyrant gets too close. Alternatively, you can run past the Tyrant with Billy in front and attack it with a knife when possible. If it targets you, run away as Rebecca has low stamina.

Solo (Rebecca): The Tyrant will crouch and charge at you when it intends to attack. A useful tactic is the 'merry-go-round' method: hit it once with the shotgun, run around it, wait for it to turn, then run around again. Get close to attack or knife it, then repeat. This is effective as the Tyrant struggles to turn quickly. Always run around its weaker hand to avoid damage if your timing is off. Use the magnum if you run out of shotgun ammo.

Using the Tyrant's Weakness: When hit by a powerful weapon, the Tyrant will crouch. Wait for it to stand up before attacking again, as it takes no damage while crouched and attacking during this time will leave you exposed due to weapon recovery time.

Entering the Door: Only enter the door if you are low on health, as it contains two green herbs. The corridor is small but still allows for the merry-go-round tactic.

After defeating the Tyrant, proceed to the end of the area, flip the switch, and head up the ladder. If you have both Rebecca and Billy, leave Billy here.
