## What is Sector Siege?

Build your defense and hold back the siege. Sector Siege puts six distinct tower types at your command as waves of enemies push toward your core. Choose your positions, time your upgrades, and make every bit of energy count.

A different decision can change a battle. Gameplay Analysis, powered by the Apple Neural Engine, looks back at your match to find a useful adjustment. When it finds an improvement, it shows you what to change, where to make it, and how it helped when that encounter was replayed.

• Find your combination
Mix six tower types and upgrade your defenses to meet the next wave. Experiment with placement and discover combinations that keep enemies from reaching your core.

• Set the pace
Pause to consider your next move or speed up the action with three game speeds.

• Get closer to the action
Survey the arena from above, pinch to zoom, drag with two fingers to move the camera, or twist with two fingers to rotate. Switch on TV mode for a cinematic view.

• Hear the battle around you
Spatial Audio brings another dimension to the shots, impacts, and explosions.

• Make your next run count
Compete on the Game Center leaderboard and earn achievements as you reach milestones and clear waves without a breach.

• Pick up where you left off
Your progress saves automatically, so you can return to an unfinished game.
