Found a secret room in the Asylum by complete accident. Now I'm cursed to forever press w on every inch of every map.
So, you find that doctor room. The funny thing is, you can find note in your base near location you appear after mission. Its an add for cure, if you have "ghost desease" after failing ghost capture (i believe). And it tells you how to get to that room. Its literally under your nose. You just didn`t meet the right circumstances i guess
