Crystal Sphere



The Crystal Sphere is an addition to the player's heads-up display in the Catacomb Adventure Series. An evolution of the Compass from Catacomb 3D, the Crystal Sphere is much more useful, not only showing the player which way is north, but functioning as an early-warning system of sorts, giving the player the real-time positions of enemies relative to the player on the sphere. The player's shots also show up on the Sphere.

A very useful piece of equipment, the sphere has only two flaws; it will only detect enemies aware of the player's presence, and it can't detect most enemies on its own. To upgrade its effects, the player will need to find Jewels that will let it detect additional enemies.

Without the appropriate Jewels, the Crystal Sphere will only detect minor enemies, such as Bats, and Nemesis.

In Catacomb Apocalypse, the Crystal Sphere is vitally important because of its ability to expose the location of Invisible Horrors, which are only minimally visible with the naked eye.
