Hollow Ground

A Top-Down Shooter that builds upon classic 90s shoot 'em up arcade games
Play solo or with up-to three friends in local or online co-op. Take control of four mercenaries as they descend into the Epsilon 9 bunker. Descend 40 floors deep into the bunker to unearth its mystery, save the world and destroy chaos manifest: The Machine.
Hollow Ground was originally released in 2003 for Mac and this version has been built from the ground up to play exactly like the original game.
Explore 70+ handcrafted labyrinthine levels

While navigating through the labyrinthine tunnels of the post-apocalyptic Epsilon 9 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.

Traversing every level is its own perilous puzzle.

Every journey down the bunker is unique

Traverse 40 floors to reach the bottom of the bunker!

The 70+ maps appear in a somewhat random order so that no attempt is the same.

Four mercenaries make the unwelcome journey to rid a war

The rag-tag band of mercenaries have to save the world from a new threat of extinction, a terrible biomechanical weapon of mass destruction.  
Each armed with 4 distinct weapons.

Unique strengths, weaknesses and synergies with cybernetic upgrades.

Purchase upgrades and powerups

Strewn across the wartorn halls are credits for use in the shops that appear between levels. Spend said credits on:
Medkits

Weapon upgrades

Single use psionic abilities

Cybernetic upgrades

Cybernetically enhance your character

Each character has 8 available slots.

Fit chips that make the character stronger, faster or in other ways better!

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.
