Idle Mastermind

& lt;p & gt;Idle Mastermind - While other superheroes think how to save the city from you, make a mess around and carefully think through sinister plans! Build a secret lair with various rooms in a non-conspicuous place, collect brutal murderers and other villains, make surprise raids on the city and lead the whole process for many years. A laboratory, a meeting room, a testing room, a room for professional programmers and a room for large mechanisms are all that you will need. Create amazing things and go down in history, not in the best way.
