AI War: Fleet Command is a space strategy game from Arcen Games in which humanity has already lost its war against artificial intelligence. Machine forces control most of the galaxy, and you start with a small foothold that has to grow without drawing too much attention. The AI reacts to how aggressively you expand, so every planet you take raises the threat against you.
It plays as a large-scale real-time strategy game with a heavy layer of long-term planning, and campaigns can run for many hours. You can play alone, or team up with friends in cooperative games online or over a local network. It suits patient strategy players who enjoy difficult, asymmetric challenges.
