"Branching AI timelines with consequences that stick, past a brutal first hour"

About

Heart of the Machine casts you as the first sentient AI, waking inside a near-future city with no fixed goal beyond survival and influence. It folds 4X expansion, a turn-based strategy layer, and city-builder infrastructure into a structure driven by story chapters, each completion unlocking new mechanics. You build machine armies, hack corporate security, manipulate gangs, and decide whether to rule from the shadows or move openly, while a Dimensional Time Travel system lets choices ripple across rewound timelines. Minute to minute you move tokens on a rendered city map, manage production chains, and weigh decisions that carry consequences across runs.

Verdict

Heart of the Machine does something most strategy games never attempt: it makes the story and your choices the engine, not a backdrop, and the branching timelines reward you for sticking around through multiple endings. The catch is the door. Its interface and early hours are genuinely off-putting, and some players bounce before the design opens up. Those who climb the wall find one of the more singular strategy RPGs around, and Arcen's steady patching suggests the rough edges are being filed down. Worth the effort if you have patience for the first few hours.

You'll like it if …

  • +you want choices that compound across runs rather than reset
  • +you enjoy decoding an unusual ruleset on your own terms
  • +AI sentience and morally murky worldbuilding pull you in

You'll dislike it if …

  • you need a clean tutorial and a readable interface from minute one
  • you want tactile, weighty combat over deliberation
  • broad systems that stay shallow individually frustrate you

Breakdown

Gameplay
  • +The genre blend is genuinely hard to pin down, and that strangeness is most of the draw
  • +Losing a run often counts as progress, which softens failure into momentum
  • +Turn-based pacing gives room to read the city and plan moves deliberately
  • City expansion and resource management slide into repetition over long sessions
  • Combat and infrastructure building work but feel clunky and thin next to dedicated strategy titles
  • A vocal minority finds the systems broad but superficial, with too few decisions that bite
Depth
  • +Branching timelines and multiple endings mean two runs rarely look alike
  • +Each chapter unlocks fresh mechanics, so the systems keep widening rather than repeating
  • +Decisions echo far down the line, and players report dozens of hours before reaching even a second ending
  • The density of interconnected systems can swamp newcomers before any of it clicks
Atmosphere
  • +The writing carries the game: AI sentience and ethics handled with real bite
  • +Worldbuilding leans into the grotesque, from bioengineered raptors to harvester spiders
  • +Story is welded to your choices rather than playing out beside them
  • The script sometimes humanises the AI protagonist more than the premise warrants
Presentation
  • +The art style looks odd at first but pairs cleanly with the systems and makes the map easy to read
  • +Soundtrack and sound design draw consistent praise
  • +No reported performance trouble
  • Presentation is token movement on a slowly shifting city render, not cinematic action
Polish
  • +Players who push through report the interface becomes learnable
  • +A simplify-production-chain option exists for those who want less micromanagement
  • +Arcen patches actively and responds to feedback, a point reviewers single out
  • The UI is the recurring complaint: confusing layout, information dumped faster than you can absorb it
  • Onboarding leaves some players two hours in with no grasp of what they're doing
  • The early game is obtuse to the point where trial and error becomes guessing
