Compatible with Krastorio 2 Spaced Out and its respective science progression on Factorio 2.0; temporarily removed for 2.1 as Krastorio 2 Spaced Out has not updated for 2.1 yet.

2.0

Mining productivity was already pretty powerful, and Space Age made it even cheaper, in addition to numerous other options that combine with it multiplicatively. This mod restores the base game cost, making levels 3+ follow Space Age progression tiers, and puts infinite research at Promethium Science.

1.0

The first release remains available and merely sets the cost to that of the base game, putting infinite research at Space Science.
