Build a fort. Survive the horde. Your stream chat plays too.

FortWar is a fort builder and tower defence game on one shared planet that never logs off. Claim a hex, mine crystal, build walls and turrets, and upgrade them until they glow. Every 40 seconds the horde comes for it, day and night, and your fort keeps fighting while you're away.

Raid rival commanders, clear monster nests, and link your Twitch chat: !join spawns viewers as defenders, !support powers a turret, !charge fills an orbital strike and !boss names the next boss.

Built live on stream with Claude Code and three.js. Idea by Jeff.
