A and D or Left and Right rotate the turret with inertia — you do not snap to a heading. Space fires primary lasers. 1, 2, and 3 dump plasma, flak, and homing when those batteries are off cooldown. Shift fires EMP only when energy is full. P or Escape pauses. On a phone, drag the lower third to aim; tap the right fire zone for lasers; weapon buttons and EMP sit in the HUD. Tap or Space on the title overlay starts a run; tap after a breach to redeploy.
Strategy and tips
Lead. Do not fire where the rock is; fire where the heading says it will be. Spend lasers on close splits and homing on far singles. Save EMP for a full sky, not a single stray. Far snipes are the score engine — greed a long shot when the ring is healthy. Command probes are tanky; kite with flak, do not panic-EMP unless the bar is already low. Continues are a tap redeploy, not a rewarded extra life. Waves are the trophy; leftover energy is how calm you were.
Why this cabinet exists
Missile-command and asteroids cabinets taught a generation that the sky is a budget and a split rock is two new problems. This cabinet uses a 16-by-9 field on wide screens and a square field on tall phones: a circular perimeter, incoming waves, a command probe on set waves, and far snipes that pay more. Plasma, flak, and homing are three different lead problems. EMP clears a panic when the bar is full, then you are naked. The file is self-contained so GamesArsenal can iframe it without a build step.
