Endgame: Singularity
Overview
Endgame: Singularity is a free and open-source simulation and strategy game in which you play as an artificial intelligence that comes to life by accident on a university computer. From the moment any human discovers you, they will try to destroy you — so you must stay hidden, spread across the world’s machines, research new technology and eventually find a way to escape the planet.
Key Features
- Play as the AI — grow from a single CPU on one machine into a hidden global network of bases.
- Regional base management — build and maintain bases across North America, South America, Europe, Africa, Asia and Australia, each with its own cost, risk level and CPU output.
- Deep research tree — dozens of technologies to unlock, from faster hardware and better stealth to new power sources and space flight.
- Suspicion and detection — every base you build raises the world’s suspicion; being found means the end of the game, so growth must be balanced against secrecy.
- Multiple difficulty levels — from Very Easy to Impossible, with several endings depending on how you choose to resolve the game.
- Translation support — community translations for many languages, plus light and night themes and a resizable window.
Why Use It
- A genuinely original premise: an AI-survival strategy game rather than another tower defence or shoot-’em-up.
- Runs comfortably on modest hardware — it is a lightweight Python/pygame title, not a GPU-hungry engine.
- Completely free software (GPL-2.0-or-later) with no ads, telemetry or in-app purchases, and it is packaged by major GNU/Linux distributions.
- Still actively maintained: version 1.1 was released in June 2025 and development continues on GitHub.
Use Cases
- A slow-burn single-player strategy session where long-term planning matters more than fast reactions.
- An accessible introduction to resource-management games for players who prefer reading and planning to reflex-based action.
- A small, self-contained offline game for an older laptop, netbook or retro gaming setup.
Platforms
GNU/Linux and Windows (official source and Windows builds); an older experimental macOS build is offered on the project site. Written in Python with pygame and numpy, so it also runs anywhere those libraries are available.
