The main perspective places the player behind a defensive launcher or within a three-dimensional battlefield. Incoming attacks approach cities, installations, or other targets, and the player moves a targeting cursor before launching interceptors.

Modes reinterpret the original game in different visual and structural forms. Success depends on destroying threats before impact, managing available defensive resources, and protecting enough targets to continue. Rounds become faster and more demanding, while surviving stages advances the player through increasingly intense attacks.

Prioritize missiles that are closest to protected targets rather than firing at distant threats. Use each explosion to catch groups of nearby projectiles when possible, and avoid wasting shots on targets already covered by another blast.

Watch the whole battlefield instead of fixating on one attack lane. Preserve defensive resources during manageable waves, then respond quickly when several targets are threatened at once.
