Heat Signature

 is a science fiction game from Tom Francis, the creator of Gunpoint.

Overview
The title refers to the thermal radiation emitted by objects in space, including stars, planets, satellites, and spaceships. The point of the game is to find and infiltrate randomly generated spaceships, to steal vital goods or assassinate characters. There is no current end game planned, as the game is supposed to be played indefinitely. The game is developed as an unforgiving, top-down roguelike with permadeath, where one shot kills.
