Tom Francis and Suspicious Developments, perhaps best known for creating 2013's seminal stealth-puzzle game Gunpoint, have announced that his new title Heat Signature will come out on Steam on September 21.

The game, announced in 2014, might be best described by its simple tagline: "Heat Signature is a game where you break into spaceships, make terrible mistakes, and think of clever ways out of them."

Check out the game's ten minute trailer from a few months back below. There are also launch-week celebrations coming, including a contest to get a Steam card drop named after you.
