Fleets and combat

Sending a fleet

• Fleet slots: you can have one fleet flying, plus one per level of Computer Technology.
• Speed and fuel: a fleet flies at its slowest ship's speed, and you can send it at 10–100% of that. Flying slower saves deuterium but takes longer. Check arrival and return times before you send.
• Missions include transport, deploy, colonize, espionage, attack, ACS attack, recycle, and expeditions or excavation at position 16.
• You can recall a fleet in flight from Fleet → Movements.

Spy first

Send Espionage Probes before attacking. The report, delivered to Chat, shows resources and, with enough Espionage Technology and probes, fleets, defenses and more. A missing section means your probes didn't see it, not that it's empty. Probes can be destroyed.

Battles

• Battles last up to 6 rounds. Each side's ships and defenses fire at random targets, and some ships have rapid fire against particular targets.
• Weapons, Shielding and Armour Technology each add 10% per level to attack, shields and hull.
• Defenses don't fly, but 70% of destroyed defenses are rebuilt automatically after the battle.
• A draw happens if both sides survive the last round.

Loot and debris

• A winning raid takes up to half of each resource on the planet, limited by your fleet's free cargo space.
• Destroyed ships leave a debris field of 30% of their metal and crystal. Only Recyclers can collect debris.
• Big battles can create a moon: 1% for every 100,000 debris, up to 20%. See Moons.

Before you risk your fleet

Use the Simulator to estimate a battle from a spy report. It's an estimate: real defenses change, reports can be incomplete, and battles involve chance. Look at your expected losses, not just who wins.

Attacking together (ACS)

Alliance members can combine fleets into one ACS attack. Launch an attack, create a union from Fleet → Movements, and invite allies to join it. Allies can also send a Hold Position fleet to station at your planets and defend them.
