On its opening moment, the Spacebank's designer declared it to be unheistable because of the relativistic time effects of its close orbit around a black hole. Someone did a heist in the very next millisecond. Since then, the spacebank has been heisted over one billion times, regardless of the number of armed guards, bombs, trap mines, or missile launchers used to defend it. You are the latest heister, ready to make your space fortune, and it would be so embarassing if you were the first one to actually get caught.
