Core Mechanic
Your Radar Is Your Eyes
A descending green sweep line reveals threats hidden in the fog. Amber blips mark incoming contacts. As the sweep crosses a threat it ghost-reveals as a green silhouette — you can read its heading and type before it enters firing range.
Stay ahead of the sweep. React early. Survive longer.
How to Play →Three Escalating Threats
Every leg raises the spawn rate and shifts the threat mix. The strait gets worse.
Sea Mines
Drift slowly down the corridor. Predictable but deadly if you're not watching your lane.
Patrol Boats
Fast-attack craft that home in on your position. Require quick missile responses.
Drone Swarms
Three drones cross in staggered formation. High target count, tight timing.

Built for One Thumb
↕ Steer
Hold and drag anywhere in the lower screen. Your vessel eases toward your thumb offset — you control direction, not exact position. Natural virtual-analog feel.
🎯 Tap to Fire
Single tap launches one strike missile at the nearest threat (1 charge). The missile tracks in real time — just fire and steer.
⚡ Hold for Salvo
Hold 0.7 seconds to unleash a heavy 3-missile salvo (2 charges). An amber ring charges at your thumb so you can feel the timing without looking at the HUD.
📦 Grab Airdrops
Parachuted supply crates drift down the corridor. Steer into green crates for hull repairs (+HULL) or amber crates to refill your magazine (+AMMO).
Choose Your Side
Rome or Persia — two ancient empires, one strait. Your vessel flies that standard at its stern; every hostile boat flies the other.
