Fly your tiny defenceless pod up to larger ships, dock with their airlock, and sneak inside. Once you're in, you creep through their corridors, ambushing guards, hiding bodies, stealing new weapons, blowing them up from the inside, or hijacking their turrets and even the whole ship.
Official system requirements
Heat Signature isn't on Steam, so we don't have official Steam-published specs to display. Our 2026 hardware recommendations above are based on real-world performance testing and similar-title comparison.
Can your PC run Heat Signature?
Check the manufacturer's launcher (Battle.net, Riot Client, Epic, etc.) for specific requirements — most live-service titles run well on a modern entry-level gaming PC.
