Hollow Ground (AppID: 3997920)

A Roguelike Shooter that builds upon classic 90s shoot 'em up arcade games

Explore 60+ handcrafted labyrinthine levels

While navigating through the labyrinthine tunnels of the postapocalyptic Epsilon bunker you will battle armies of mutated creatures and nefarious robots. The tunnels are laden with machinery of at times ambiguous intent such as keycard doors, teleporters, switches and timers causing havoc. This makes traversing every level its own perilous puzzle.

Every journey down the bunker is unique

Due to the 60+ maps appearing in a somewhat random order replayability is greatly enhanced.

Four mercenaries make the unwelcome journey to rid a war

The rag-tag band of mercenaries each armed with four unique weapons have to save the world from a new threat of extinction, a terrible biomechanical weapon of mass destruction.  

Purchase upgrades and powerups

Strewn across the wartorn halls are credit chips for use in the shops that appear between levels. Spend said credits on medkits, weapon upgrades, single use psionic abilities and cybernetic upgrades.

Cybernetically enhance your character

Each character sports eight cybernetic upgrade slots, allowing for flexible build variety. Upgrade effects range from simple stat increases to a live minimap and auto firing seraphims.

Time is not on your side

Due to radioactivity your health is steadily decreasing for every second you spend in the bunker. Sometimes forcing an early exit from a floor even when there is still treasure to be found.

Enhance the game with jolly cooperation

Play up to four players either locally or over the internet. But be warned bullets hurt you as much as it hurts the vermin of the bunker. 

Make and share your own levels

The game ships with a built-in level editor allowing users to create and share their own maps via the Steam Workshop.
