Legendary Tips

  • The final Warthog run is on a strict timer: hold the center line, never stop to fight, and remount instantly if you flip (community).
  • Rocket Flood one-shot you on Legendary in the engine room - clear each platform at range before jumping (community).
  • Regenerating health gives the escape run a little extra forgiveness in the remake.
