Unfortunately, Heat Signature’s structure lets it down somewhat. It becomes a repetitive grind, broken up by the occasional amazing moment. The procedural generation makes it feel special, randomly creating an environment for these unique anecdotes, but it is a double-edged sword as there are a multitude of uneventful missions in-between. Still, it all feels worth it for those moments when there are a few seconds left on the clock and you are forced to take desperate action.
