You are some thief doing small time robbery with low income houses and working your way up to richer houses with security you see in the Hitman games. It is almost a Payday simulator without the shooting or drilling. There is a safe cracking kit that opens safes and is much faster than drilling. You open windows by breaking them, then move up to glass cutters. Open doors with lockpicks, electronic lockpicks, going up to remotely hacking security systems.
Game is still a little janky and getting patched.
