Aliens

Aliens are pushing into your universe through black holes. The fight against them runs in attack waves: each wave lasts one week and starts over every Friday. For every wave you assemble a fleet and use it to attack black holes – without losing any real ships.

Requirements

Battles against aliens unlock at an attack power of 10,000 (tactical fleet strength). Tactical fleet strength only rates your ships, without defenses, and it has its own ranking (Ranking). You cannot take part while in vacation mode or spectral mode.

How a wave works

1. Assemble your fleet: Pick the ships for this wave on the alien page. You can only commit part of your tactical fleet strength – the page shows how much as "available (tactical) fleet strength".
2. Reinforcements: Once per day you can add more ships to your wave ("request reinforcement").
3. Attack black holes: Find targets with the Alien scanner or on the galaxy map and launch the attack from one of your planets. Every attack uses up part of your wave attack power. The ships themselves return unharmed.
4. Collect your reward: On arrival you receive Spice and war emblems, and red black holes and the boss also give mentor stars for your alliance.

Rewards and limits

• Spice: Each wave has a personal Spice limit that depends on your universe, your number of planets and your fleet share – the question mark next to the display shows the breakdown. On top of that, each attack only brings back as much Spice as fits into the cargo holds of the ships you sent.
• War emblems: Trade them for bonuses in the Emblem shop. There is a cap per wave here too.
• Mentor stars: Go to your alliance and support mentoring (Mentoring program).
• Attack limit: The number of alien attacks per wave is limited, and you can attack each black hole only once per wave.
