Get Started

Amp is a short-form wave shooter for iPhone. You control the horizontal position of your formation; soldiers and turrets fire automatically.

Start a Stage

1. Select an available stage on the title screen.
2. Drag left or right to line up your formation with incoming enemies.
3. Destroy each wave before it reaches the defense line.
4. Focus fire on one of the upgrade gates when the route divides.
5. Defeat the boss to clear the stage and unlock the next destination.

Touch Controls

• Aim: drag anywhere in the play area to move the full formation left or right.
• Choose a gate: line up the formation and its fire with the upgrade you want.
• Pause: tap the pause control during a stage.
• Account: open ACCOUNT to protect, load, or delete saved progress.

How Combat Works

Amp has no attack button. Every soldier and turret fires straight ahead at a fixed interval, whether or not an enemy is currently in the lane. Move the formation to place those firing lines over the targets you want to hit.

Enemies that reach the defense line remove soldiers. Upgrade gates can add soldiers, increase damage, or add turrets. The selected upgrade applies immediately and remains active for the rest of that stage.

Saved Progress

Current, unlocked, and completed stages are saved automatically on your device. When the network is available, Amp creates an anonymous guest account and synchronizes the same progress with its service.

Local saving continues while the network is unavailable, and progress synchronizes again after the connection returns. You can add an iOS passkey from ACCOUNT to protect the save and load it on another Apple device.
