About Mainframe Defenders

Mainframe Defenders is a tactical strategy game set in the “Stargazer” research complex, where a computer virus has taken control of most robotic units. You lead a squad of four prototypes to defend the complex’s Mainframe and push into its deepest areas.

Missions in Stargazer

You repel assaults, destroy unit fabricators, download valuable data and clear infected nodes. Missions combine different objectives with unique conditions, and their levels pair hand-made rooms with procedural generation. You can accept the challenge of the unknown or avoid it and risk falling behind.

Build your squad

Combine items with unique abilities to create powerful squad builds. Items have limitations and drawbacks, which you can work around or build upon. Victory or defeat, you can unlock new units with their own upgrades and load-outs, as well as new items for developing further strategies.

Tactical combat

You can overheat enemies, damage them with corrosion, absorb attacks and return fire, bury opponents under bullets, eliminate them with a powerful shot or disable them with debuffs. Enemy units have distinct roles and are designed to counter particular strategies, so you need to choose targets carefully and avoid relying too heavily on one approach.

Retro presentation

The graphics take inspiration from 1980s terminal PCs, accompanied by a synthwave soundtrack.
