HotLead is an arcade third-person shooter set in industrial surroundings. The game takes the players in a world where mankind has reached the deepest corners of space and has encountered new alien species. Humans wanted to defend themselves in the event of a war for space supremacy and built droid bases on strategic planets, which were each supposed to protect a certain area and launch a defensive attack in the event of war.
But the war never came and the droids were left abandoned, while their mission still remains the same – to attack anyone that might seem hostile. This leaves open the possibility of a battle happening by chance any time, where droids could attack even a peaceful visitor.
