Those who already know about this game and how much they've missed it don't let me hold you up any further, your link to download is right here. For the rest of you, Dungeon Keeper is a strategy simulation type game where you play the boss of a dungeon.
You aren't the kind of boss who sits in the final room and has a vital weak spot, however, you have to run this place! That means enslaving imps to build the various traps in your dungeon, hatching chickens to feed the numerous monsters housed within your pit of despair, and slapping minions around occasionally to make sure they don't get too high and mighty.
Most important of all, your job is to prevent any and all heroes from completing your dungeon. It's a lot harder than you think.
For example, some creatures can't be placed in the same rooms as they're natural enemies. If you set two monsters who don't get along in a room they'll kill each other before the hero even enters! You'll find yourself scratching your head as you fend off armies and powerful heroes who enter.
It even had multiplayer, which was a big deal in 1997. Did I mention you can switch from third person and possess your minions at will?
Even if you're on the fence about this game, it's free on Origin right now. Don't put it off and miss out on getting a great game on the cheap!
