ZXSpace Tips & Strategy

Your cities are your most valuable resource. Destroy alien formations before they break through your shields and reach the buildings below.

Losing a city reduces your chances of surviving the later waves, so prioritise defence over chasing every bonus enemy.

Keep your cannon moving rather than waiting in one location. Good positioning allows you to intercept enemies, collect power-ups quickly, and react to sudden threats.

Try to stay near the centre of the battlefield whenever possible so you can reach either side before enemy formations become overwhelming.

• Avoid staying in one position for too long.
• Keep the centre of the battlefield covered.
• Move early rather than reacting at the last second.

Shields provide valuable protection, but they won't last forever. Use them to absorb enemy fire while you reposition your cannon or prepare your next attack.

Repair damaged shields whenever a Shield Repair power-up appears to keep your defences strong throughout the game.

• Repair damaged shield sections whenever possible.
• Avoid letting aliens repeatedly attack the same area.
• Protect weak sections before they collapse completely.

Power-ups are most valuable when the battlefield becomes crowded. Saving offensive upgrades for the busiest waves allows you to destroy more enemies while reducing pressure on your cities.

Emergency power-ups such as EMP Pulse and Smart Bomb can completely change the outcome of a difficult wave when used at the right moment.

• Save offensive upgrades for busy waves.
• Use Shield Repair after heavy damage.
• Keep EMP Pulse and Smart Bomb for emergencies.

Higher-value enemies and bonus UFOs can dramatically increase your score, but don't risk your cities simply to chase bonus targets.

Collect a Score Multiplier before large enemy formations whenever possible to maximise the points earned during its active duration.

Every completed game teaches you something about enemy movement, wave patterns, and power-up timing. Small improvements quickly lead to longer survival times and higher scores.

Focus on surviving consistently before attempting risky high-score strategies.
