Swarm
Our take on the 1981 arcade classic Galaga. Forty enemies swoop in and form up, then peel off to dive at you. Let a boss catch your fighter in its tractor beam, then shoot the boss on its next dive to win the fighter back and fire double.

On a phone or tablet, hold a finger on the screen. The fighter follows it and fires on its own. A gamepad works too.
- The formation
- Each stage, forty enemies fly in over five waves and take their places. Once they're settled they start to break away and dive, and they dive more often the further you get.
- Bosses
- The green bosses take two hits. A boss that dives with two escorts is worth up to 1,600 points if you shoot the escorts first.
- The tractor beam
- Sometimes a boss stops above you and lowers a beam. If it catches your fighter, it carries it back to the formation. Shoot that boss while it's diving and your fighter comes back to dock beside you. Shoot it while it's sitting in the formation and your old fighter turns against you.
- Challenging stages
- Stage 3, and every fourth stage after it, is a bonus round. Forty enemies fly past without shooting. Each hit scores 100, and hitting all forty earns a 10,000 point bonus.
- Extra ships
- You start with three fighters and earn another at 20,000 points, 70,000, and every 70,000 after that.
