I very much like designing games but I also like to play games.
Metallum is my first game that will be premiered in Essen.
1. As far as planetary modules are concerned they are always active (example force shield always protect your extractor). So you can constantly use abilities of all your planetary modules.
NOTE: some of the planetary modules "actually do something" only at a specified time (example factory: produces your extractor at the start of programing phase) so while they are technically active all the time they only perform their action at specified time.
2. Action modules can be used only once (usually right after you buy it or at a specified time later).
