I have only one lacking thing which I can't discover/encounter. Already have maximum Mars Level (35) which unlocks rest of buildings/leaders and lifeforms.

Does somebody know what's that locked building, and how to get it?

The locked building is in "uncommon" class between those unlocked ones

Update: I got information, that locked building was Marsolympic Stadium! Turn after picking to host those, got required card and now have full collection of Marsyclopedia :)
