Heart of the Machine, a city-building sandbox game by Arcen Games, launched in early access in January 2025. It combines elements of 4X strategy, RPG-like narratives, and tactical combat. Following a significant update that eased some challenging endgame elements, players requested a return to the original difficulty, leading to the introduction of 'Misery mode,' designed for those seeking extreme challenges. The game has been adjusted to make key routes easier for new players, and it allows exploration of alternate timelines. Arcen Games is working on finalizing tier-three goals for the game's eventual 1.0 release, with a planned post-launch update for the 'Stars Beyond Reach' route. Heart of the Machine is currently available at a 50% discount during the Steam Winter Sale, priced at .99 / £12.49, and has a 92% positive recommendation rate from players.
