Giant mantises are mutated insects found in the Mojave Wasteland in 2281.

Characteristics[edit | edit source]

Biology[edit | edit source]

Giant mantises are mutated praying mantises created by the horticultural experiments that took place in Vault 22. They have since escaped from the vault and have spread into the Mojave Wasteland. Compared to other mutant creatures, their biological traits have remained relatively unchanged when compared with the original specimen, except for significantly increased size. They are still much smaller than humans, but make up for that by attacking in swarms whenever possible. Mantis eggs and mantis forelegs may be taken from their dead bodies.

Gameplay attributes[edit | edit source]

Because of the height difference, giant mantises' attacks mainly consist of jumping and slicing its target in mid-air with their forelegs. If a mantis' antennae become crippled, it will become frenzied and the mantis will begin to attack anything within reach. There are quite a few mantises on the way to Jacobstown and around Spring Mt. Ranch State Park.

Variants[edit | edit source]

This variant is the standard giant mantis encountered later in the game around Spring Mt. Ranch State Park or on the way to Jacobstown. They can be found in groups or scattered around these areas when encountered. This variant is also the majority of mantises encountered in Vault 22.

Notes[edit | edit source]

  • Taking two or more mantis forelegs off of one will cause the model's forelegs to explode. This does not occur for mantis nymphs or giant Zion mantises.
  • Shooting a mantis ootheca will release a dozen giant mantis nymphs, which will then attack.
  • When observed for a time, a mantis can be seen cleaning its mouth. On occasion, it will flutter its wings the same way it would when attacking.

Appearances[edit | edit source]

Giant mantises appear in Fallout: New Vegas and its add-ons Honest Hearts and Old World Blues.

Bugs[edit | edit source]

PCIcon pc.png The mantis XP glitch still remains with Zion mantises. A transfer of legs could lead to 200 XP gained at a time, dependent on level. [verified]

Sounds[edit | edit source]
