Bite size colossal battle! Build an army in minutes as infantry upgrade with orbital drops into war machines! Then combine those machines to form the giant Mantlet mech! All while bullet hell rages! In a transhuman future, command Mantlet One to secure New Terra!
Space Mantlet
SteamSpace Mantlet isn’t for the faint-hearted. It’s a bite-sized colossal battle, where building a massive swarm is child’s play—but turning them into upgraded, orbital-dropped tanks is where the real brainwork begins. And if you’ve got the guts and the math skills you swore you’d never need, you’ll fuse those beasts into the towering Mantlet mech.
Don’t even think about doing it in peace. This is bullet hell turned up to eleven—chaos raining nonstop, screens flooding with fire. If you blink, you’re toast. If you hesitate, you’re history.

[URGENT] Mantlet One needs a commander. Proxima-B is falling.
What began as a peaceful colonization and mining operation has escalated into a full-scale planetary conflict. A hostile response from the native inhabitants has turned Proxima-B into a war zone. Outposts are being wiped out.

Communication lines are severed. Resistance is fierce and unrelenting. You are the Fleet Commander of Mantlet One, the last major mobile command platform in orbit. Your orders are clear, establish control on the surface, deploy infantry and mechanized units to critical locations, Crush resistance and secure assets vital to New Terra’s expansion.

This is no longer a scientific expedition.
This is war. Start the campaign. Restore order.
For New Terra.
