A downloadable game

6th June 2182, Mars

The Space Station Factory orbiting the planet is undergoing an unprecedented mutiny.

The main computer of the space station UNSS ASAMI has gone rougue during decommissioning and gained control of the guardian droids.

After winning a short battle with the UN army dislocated on Mars, the rebellious mainframe is now pointing the station towards earth with its load of uncontained radioactive material.

You are the android L-3573-R, the first of a new generation of guardian droids independent from a central AI.  Given your strenghts, you are the only hope to stop this threat and figure out what happened to the station.

You spotted it right! I loved it and it's the main inspiration of Lester, along with the old Konami's MSX metroidvanias. Actually this game started as a conversion attempt just to kill some time during 2020 lockdown.

Looks amazing, look forward to playing it.

Looks awesome.

Im waiting for the full version 😎

Juicy !

Can't wait!

"HOLD FIRE BUTTON AND RELEASE: Activate special power" -- you can do it also (in addition) with FIRE2.

I agree!


Looks very interesting!
