ROOM-SCALE TACTICS

Three moves. Endless routes.

Your furniture, floor, and point of view turn every deployment into a different tactical problem.

01⌖

Scan the room

Move slowly across a well-lit floor or tabletop while ARKit finds the surface and maps raised obstacles.

02⌗

Shape the route

Drop solid towers to bend the ground path. The route validator never lets you seal the final way through.

03⌁

Counter the swarm

Track ground bugs, burst aerial threats, chain lightning, slow the lane, and push flyers back into range.

REAL BUILD // LIVE SYSTEMS

A battlefield with rules you can trust.

Every placement is checked before it lands. Ground bugs pursue the least-cost open route; flying bugs ignore placed defenses, meander independently, and still route around mapped room obstacles.

✓ 30° forward play sector
✓ 7 × 12 tactical grid
✓ Dynamic target tracking and projectiles
✓ Environment-aware PBR lighting

THE INVASION

Built to look alive. Tuned to play differently.

Ants sprint in numbers. Beetles soak fire. Scorpions arrive armored and dangerous. Mosquitoes and wasps meander above your carefully built maze. Any survivor that reaches you lunges at the lens with bite or sting feedback.

Ground species scurry with distinct six- or eight-legged gait timing while mosquitoes and wasps beat their wings in a fast mirrored buzz. Each bug owns an individual cadence, so a wave moves like a swarm instead of a synchronized parade.
