Find a surface
Hold the iPhone in portrait and move slowly across a clear, well-lit floor or tabletop until tracking locks.
FIELD MANUAL // REV 1.0
Win the room before the swarm reaches you.
Room Siege AR combines spatial setup, path-building, target counters, and an earnable permanent arsenal.
01 / DEPLOY
Place the battlefield
Choose the approach
Face the direction the invasion should enter from. Each level gets a resettable 30° forward sector.
Confirm the field
The 7 × 12 grid lands on the surface. ARKit maps classified raised surfaces into route-safe obstacles; LiDAR devices add denser scene-reconstruction detail.
02 / ROUTE
Bend the path. Never break it.
Solid towers block tiles and force ground bugs onto the least-cost route to your barrier. Every placement is validated, so the final route can never be closed.
SPAWNYOU
Hazards steer instead of block
Shock and Glue Pads remain traversable but add path cost. Bugs prefer a clean detour—unless your layout makes the dangerous lane their best option.
Air plays by different rules
Mosquitoes and wasps ignore placed ground blockers and receive individual meandering approaches around scanned walls, each roughly 1.5× the direct grid distance. Flak, Frost, and Fan defenses add damage, slowing, and pushback.

04 / THREATS
Read the swarm
Every production insect has its own physical scale and motion profile. The beetle is a photographically textured Smithsonian museum scan. Ants, roaches, and beetles use alternating tripod steps; spiders and scorpions alternate four leg pairs; mosquitoes and wasps beat mirrored wing pairs at species-specific buzz rates. Individual timing keeps neighboring bugs out of lockstep, while Frost, pause, and combat speed change motion and travel together.

05 / CAMPAIGN
Fifteen sectors. Five escalating chapters.
Each five-wave sector introduces threats gradually and adds a tactical directive. Clear the sector for one star, protect at least eight integrity for another, and complete its unique directive for the third. Two stars unlock the next sector; cleared sectors remain replayable for gears and a better rating.

★Three-star mastery

⌁Distinct field conditions
Salvage caches, power nodes, and air vents alter deployment.
↻Replay without penalty
Return for gears, improve the rating, or test a new build.
06 / PROGRESS
Two currencies. Two time horizons.
Salvage drops during a level and pays for that deployment only. Gears persist between levels and unlock your broader strategy.
Permanent, but never permanent-pressure
Upgrade tower damage and fire rate, expand placement capacity, or improve salvage recovery. Refund every spent gear at full value whenever you want to rebuild.
Optional purchases stay optional
The entire campaign and every combat upgrade are earnable through play. Gear packs offer convenience only; no defense, level, or ability is exclusive.
The first mission teaches the whole loop.
Scan, place a Shock Pad on the route, position a Pulse Turret beside it, launch, reinvest dropped salvage, and earn your first two permanent level upgrades.
If a bug survives, its live model lunges mouth-first at the lens while a red flash, bite or sting sound, and haptic strike communicate the breach. Reduce Motion keeps the warning with a shorter snap.
