Core

Core is a retro-style first-person game about a robot that burrows into the Earth to destroy it from within. You fight through levels filled with waves of enemies, advancing as doors open when you clear a wave or activate a button. Every fourth level of an Act ends in a fight against an Earth Core.

Levels and combat

Each level takes place in set locations, with no checkpoints: if you die, you restart the level. The final wave is usually harder than the others, though it can be easier depending on the level’s length. Levels have no map hazards, but some include environmental gimmicks such as lowered gravity or giant towers to climb.

Difficulty and music

The game has no difficulty settings; its difficulty is set by the developer. The music is mainly intense and fast-paced, and it can be turned off without affecting gameplay.
