Dungeon keeper?

I used to play this game like years ago, was a strategy game were basically your the bad guys, you make dungeons and kill other keepers and heroes etc, was really fun, they made a 2nd but i didn't think it was half as good as the 1st one, they were making a 3rd but it never got released :embar:

Anyone else play ? if so can anyone help me play online lol? because theres an option for it but i can't work it out :embar:
