  • Avoid getting too close with the close as the poison may hurt you. The boss can also crush the players if located nearby, which causes instant death.
  • When it climbs and stay on the ceiling, shoot the legs to take it down.
  • The weak point is the chest area .When it is dropped from the ceiling, it will be overturned for several seconds. Use strong weapons to shoot it on the chest to reduce its HP fast.


  • The model of Tyrant Crab is probably inspired or edited from the existing "Gonarch", headcrab queen from Half-Life.
