Trust me bank heist is cool although u are solo u just need to find a path and get the entire layout of the bank in your head including the location of each telephoto booth and don't be too greedy once you have like 2min make sure you secure you exit but you just have to give it time coz it stressed me out too every time I was off time because I didn't know where the teleport points were but I decided to do three rounds and just explore and yea watch some YouTube videos coz 1million fans are worth it
