About Under the Ruin

Under the Ruin - about the game

After the Calamity, the remnants of human civilization lie shattered. You will lead a tactical squad into the ruins, scavenge for supplies, and attempt to resolve the Calamity.

Squad Combat

You don't fight directly. Instead, command your tactical squad to operate fortifications within the ruins. Their skill, strong will, and seamless coordination allow them to unleash formidable mechanical might.

Fend Off the Swarm

Danger lurks in the mist as monsters surge from all directions. Deploy your forces to key positions and use the tactical command system to contain the enemy if you hope to survive.

Engineering & Machinery

Utilize engineering machinery to repair, modify, and relocate fortifications within the ruins. Exploit every bit of value these crumbling structures have to offer.

You Are Not Alone

Through design modifications, ship upgrades, tech research, and item crafting, rally survivors during daily production to effectively arm your squad.
