Such an underrated classic.
The original mod is a broken but still a classic but this one takes it to another level.

I can't seem to get this to work. At best I get it to appear in Steam, but it won't launch when you try to start a new game.

Very good mod, I like it.

I get framerate issues in large open environments, is this normal?

Also there's a bug at the end. The player can click on a certain box and skip the last battle.

Anyone know where this was posted to cause it to have over a 1000 downloads yesterday?
