The Mantis is the final Boss of Pripyat.
The Mantis appears after using the control panel at the top of the tower. The Mantis can only be damaged by RLGS-100 launchers, however it has an energy shield that protects it from one rocket before being destroyed, leaving the Mantis vulnerable until it can reconstruct the shield. The time for reconstruction is seven seconds in Easy, four seconds in Normal and one second in Pro.
Three rocket launchers will appear every wave of enemies. One player has to destroy the shield while the other players damage the Mantis. It is recommended to not use the rocket launchers until every player has one.
The Mantis usually attacks with a machine gun but can also attack with an energy weapon, which is located under the Mantis.
