Command small fleets across hostile systems. Assign weapons to every hardpoint, read the sensor picture before the enemy does, and watch real-time combat play out down to the individual shot.
Every ship is built hardpoint by hardpoint. Assign weapons, check firing arcs, and confirm a loadout before it ever leaves the yard — what you see in the editor is exactly how it fights.
Detection range matters as much as firepower. Track sensor coverage, patrol paths, and contacts on the tactical map to know what's watching you before you know what you're facing.
Beam weapons, missile salvos, evasive maneuvers — every exchange runs live, with a scrolling tactical log tracking exactly who fired what at whom, and whether it landed.
SCSI is a small-scale tactical space RTS — no base-building, no economy micromanagement, just fleet command. Missions are scripted encounters; outcomes come down to loadout choices, sensor discipline, and how well you read the battlespace in the moment.
It runs entirely in the browser, built on three.js, with no install required.
