Open playtest — in active development
Command the ascent.
A classic real-time strategy game about taking a colony off-planet. Build the economy on Earth, hold the ground, then carry the war to the Moon and Mars — where vacuum changes the rules.

Open playtest — early access, pre-release
Enlist before the war is finished.
Aether Ascent is live, free, and deliberately unfinished. The war machine underneath already runs deep — three worlds, a breathing economy, AI commanders that scheme and counterattack, superweapons that fall from orbit — but the balance, the feel, the thousand small decisions that make an RTS legendary? Those get decided by the people playing it right now. Play a match. Push where it bends. Tell us what broke, what bored you, what made you grin — and watch the changelog ship your feedback into the next build, usually within days. Early-access testers aren't just playing the game first. They're aiming it.
