Building upgrades

How building upgrades work

For the Pig iron mine, Blast furnace, Kryptonite mine, Spice mine and Fusion plant – and with the Synth network also for the Quantum Array – you can activate up to five upgrade slots each. Every active slot gives +3%, so five slots give +15%. The upgrades apply to your whole account and therefore to all your planets.

For the mines and the Blast furnace production goes up, for the Fusion plant the energy it generates. For the Quantum Array, the Synth Former generates more energy and the AI Core's chances improve (Synth energy, Former & AI-Core).

Activating slots

You find the upgrades on the Economy page in the Building Upgrade tab. For each slot you have these options:

• Free and unlimited – if you have free slots available. Their number grows with your progress (attack zone) and through the VIP program (VIP Program).
• 3 days for 10 Urplasma.
• 14 days for 40 Urplasma.
• 30 days for 80 Urplasma.

The economy page reports free slots under Problems & warnings. The bonus breakdown shows how much the upgrades add to your production.
