Okay, I have my problems with most "AI" games, but how can enemy units SEE further than friendly units?
I am playing Crossroads in the Fog scenario, and my units are staring straight at "invisible" enemy units that keep killing my units.
While I am at it, why does the enemy ALWAYS get to move or shoot first?

That's a common bug in Cookie Monster: Beelzebub Overthrown. You need the Cookie Crumble update.

I think he talks about Crushing Marbles: Boobs Overlord. In fact in this game you first have to find the Wizard to be able to see the invisible enemies.

Another day, another Galaxy b̶u̶g̶ feature, at your service!

Unfortunately if you post through the Galaxy client, it takes you to the general discussion forum and not the game specific forum. So this means no one knows what game you're talking about. If you can identify the game, I'm sure someone can help out.

He's talking about Combat Mission: Beyond Overlord .

It is common in many Player vs Computer games for the AI to cheat to appear more intelligent than it is. Sometimes they are given resource boosts, often they don't suffer the fog of war so they can target weak points in the defense without scouting. There are usually enough AI issues to counter these advantages.
