Space Purge is a top-down space shooter that puts you in command of a lone spacecraft defending against waves of alien vessels, asteroids, and cosmic hazards that sweep in from the edges of the screen.

Your spacecraft moves freely around the playfield (unlike the fixed-bottom position of Galaxy Defender), giving you full positional freedom that enables both aggressive combat and evasive maneuvering. This mobility is essential — enemies attack from multiple directions simultaneously in later waves, and the ability to dodge while firing is the fundamental skill the game develops.

Wave structures escalate in predictable patterns within each stage but introduce new enemy types at stage boundaries. Earlier enemies move in simple patterns; mid-game foes have targeted attacks and evasive maneuvers; late-game enemies fire spread patterns and deploy minions that add chaotic secondary threats.

• Progressive wave-based difficulty
• Power-ups and upgrades
• Multiple levels and stages
• Classic retro-inspired design
• Strategic depth and planning
• Full mobile touch support
• Instant browser play — no download needed
• Free to play on desktop and mobile

Space Purge follows the arcade space shooter format with free movement:

1. Control Your Ship — Use directional controls to move your spacecraft freely around the playfield. Avoid screen edges (typically lethal or boundary-stopping).
2. Auto-Fire or Manual Fire — Your weapons fire automatically in many versions. In manual-fire versions, hold the fire button continuously for sustained shooting.
3. Eliminate Enemy Waves — Enemies spawn in formation patterns from screen edges. Destroy all enemies in a wave before the next wave begins.
4. Dodge Incoming Fire — Enemy projectiles, laser beams, and homing missiles require active evasive movement. Stay mobile — stationary ships are easy targets.
5. Collect Power-Ups — Defeated enemies drop colored orbs or capsules. Flying through them activates the upgrade (weapon enhancement, shield, speed boost).
6. Survive Boss Waves — Major boss encounters occur at stage intervals. Bosses have multiple attack phases and require pattern recognition alongside sustained damage output.
7. Survive All Waves — Clear all waves without losing all shields/lives to win the stage.

• Rapid elimination of groups without taking damage builds a multiplier
• Collecting all power-ups dropped in a wave may trigger a bonus
• Boss health remaining when defeated may affect scoring

• Arrow Keys / WASD — move spacecraft in all four directions
• Spacebar / Z / X — primary fire (if not auto-fire)
• Shift / F — secondary weapon or special ability
• P — pause
• Enter — start game / confirm menus

• Virtual joystick (left thumb) — directional movement
• Fire button (right thumb) — weapon trigger
• Double-tap — activates special ability in some versions

Pro Tip: Weapon Control: - Aim the ship center at dense enemy clusters rather than single targets — spread-shot and auto-fire weapons hit multiple enemies when aimed correctly - Lead fast-moving enemies: fire slightly ahead of their movement direction

• Space Purge mastery comes from combining movement discipline with intelligent power-up management.
• Movement Patterns: - Move in consistent orbital patterns around the playfield center.

• Observe the boss attack pattern for one full cycle before committing to an aggressive approach. Most bosses have safe zones relative to their attack patterns.
• Maintain consistent medium-range distance from bosses — too close removes reaction time; too far allows bullets to converge and corner you.

High-Score Tip: Boss Fight Strategy: - Observe the boss attack pattern for one full cycle before committing to an aggressive approach.
