Atomic Heist is a sci-fi roguelike twin-stick shooter from developer Live Aliens. Players control a combat ship within randomly generated levels, aiming to steal a leaking atomic core from an overrun space station. The core gameplay loop involves managing ammunition, collecting temporary power-ups, and acquiring permanent upgrades to survive increasingly difficult encounters.
The game expands on its core mechanics with daily game modes and an Endless Arena mode for extended challenges. Players can uncover the station's backstory through exploration and by identifying enemy weaknesses to strategize their approach.
