AI War:Exo-Galaxy Wormholes
Q: I've just started a new game and there's an AI controlled Exo-Galaxy Wormhole on my home planet(s). Why is this?
A: The presence of an Exo-Galaxy Wormhole on a player's home planet(s) indicates that they're up against a Backdoor Hacker AI type. Player ships cannot pass through these wormholes, but the AI can use them to launch waves. There's no way of preventing the AI from launching waves through these wormholes, so they will need to be adequately defended for the duration of the game.
