What goes into the bonus inventory?
You get multiple productions – for example double or quadruple output for a certain time – from the Interdimensional Transmitter, from events and as rewards. If none is running, a production boost from the Interdimensional Transmitter starts right away. If one is already running, it goes into the inventory. Alien bonuses come from event shops and rewards, among other sources.
You find the inventory on the Economy page in the Bonus Inventory tab.
Multiple production
A multiple production multiplies the output of all your planets. The inventory shows the amount, factor and duration of each stored production, and you can activate it at any time – a running multiple production is then extended.
If the stored production has a different factor than the running one, its duration is converted to the running factor. Example: if a quadruple production is running and you activate a double production for 24 hours, the quadruple production is extended by 8 hours. The inventory shows the converted duration beforehand.
Normal multiple productions and event productions run separately and can be active at the same time. Both can only be extended while their remaining time is below 60 days – beyond that, the inventory shows “max” instead of the activate button.
Alien bonuses
There are two kinds of alien bonuses: they either raise your Spice limit for alien waves or the Spice yield of your alien attacks. Once activated, they apply to the current wave (Aliens). There is a cap here as well – once it is reached, “max” appears.
Capacity
Both sections have a limited capacity, which is shown at the top. The VIP program (VIP Program) and special upgrades increase it.
