Surge

Surge is a round-based enemy rush with two modes. In Attrition, you move through an environment of narrow alleyways while rock-like creatures called Golets chase you. In Labyrinth, you search a dark area for items while fleeing enemies that cannot be stopped or fought.

Attrition

Each round adds more Golets, increasing the difficulty. Slaying a Golet earns gold, which you spend on new weapons and gear; each purchase changes the gameplay slightly. You can enter Ghost to frighten enemies away, and use traps placed throughout the environment.

Labyrinth

You must collect five items and escape through a rift without being grabbed. Crying enemies pursue you, and you have no way to defend yourself, so survival depends on fleeing them.
