Mission walkthrough
-
Take Terry’s free supplies
Ride to the prison and speak to Terry before breaching the entrance. Stock up on armour and weapons; the final assault contains several large groups of guards.
-
Breach and advance
Destroy the prison doors as instructed, then fight through the entrance. Use walls and fixed structures for cover. Check towers and raised firing positions before crossing open ground.
-
Clear the prison yard
Move with Terry and Clay toward the yard and eliminate the guards blocking access to Billy. Keep explosives away from your companions and reload before each advance.
-
Confront Billy and leave
Execute Billy when the yard is clear. Return to Terry and Clay, mount the bike and follow their escape route out of the prison.
-
Return to the clubhouse
Lead the group home and watch the final scenes. The clubhouse is no longer available as a safehouse after this ending, so use the remaining safehouse for subsequent play.
Key point
Use the free weapon stop before starting the assault. The finale continues after Billy dies: you still need the prison escape and final ride home.
