The monolith is a bonus grenade unlocked upon completing Metal Slug 3D once.


The monolith, when thrown, shoots a beam into space, and then brings down a big tablet crushing any tanks or people under it. The only bad part is you have to wait a few seconds for it to take effect.

Eri monolith classic style


  • This grenade is most likely based on the Metal Slug 3 boss The Ten Commandments of Moses, which uses a nearly identical attack.
  • It is possibly a reference to the film 2001: A Space Odyssey.
