What is xAI Defense?
Play xAI Defense free at groktowerdefense.com: a SpaceXAI themed tower defense game. Place Grok Sentinel, Falcon Battery, Starlink Array, and Starship Mortar towers to stop rival AI lab creeps—OpenAI, Anthropic, Gemini, Meta AI, Copilot, and DeepMind. Earn gold, upgrade damage and fire rate, auto-advance waves, and survive all 12 waves on mobile or desktop.
SpaceXAI towers
Four placeable platforms form the arsenal. Each has a distinct role, cost, range, and delivery method—from hitscan lasers to splash mortars.
Grok Sentinel
Frontline laser sentry
Hitscan xAI laser tower with balanced range, damage, and fire rate. Best starter tower for choke points.
Falcon Battery
Long-range precision battery
Homes long-range rockets with high single-target damage and slower reload.
Starlink Array
High-cadence pulse mesh
Rapid pulse beam mesh that shreds light units; link nearby Starlinks (proximity or LOS) for combo damage multipliers via laser-link terminals.
Starship Mortar
Area-denial siege mortar
Splash mortar that clears packed creep groups on path bends.
