I played this game in 2004 when I was a kid and it was my favorite game at the time, but I tried playing it in recent times and I realized that the AI is terrible.
On hardest difficulty the AI still acts like an imbecile, but now it has perfect accuracy and it kills you as if it's a hacker with aimbot.
Is there a mod that makes them move more, take more strategical positions but reduces their crazy accuracy?
You can make a map with more and better pathing and hint nodes, but the AI behavior in general is hard coded into the executable file.
What always bothered me about the AI is that they only shoot at you as if you were the only target on the battlefield, which is annoying. They pay no attention to your team.
