OK, after reading all these threads I dug out my DK Gold disc and also installed Keeperfx
and sometimes I can play the game, other times it crashes to the desktop right after zooming in to the heart at the beginning of a level, and the log always mentions a "Divide by Zero" error.

However, I don't remember the game being completely impossible to win.

On the event that the game doesn't crash to the desktop with the "Divide by Zero" error,
If I get my dungeon set up and get a small menagerie of creatures and I happen to break through a wall where the heroes are, there are literally a hundred or more, level 10 heroes that obliterate all my creatures and just hammer on the dungeon heart and "GAME OVER"

WTF?

I agree this game gets to a point of damn near impossible. I am on a level (dont know the name) where you are given a premade dungeon and heros come at you from 4 directions at a constant rate. If anyone knows the level im talking about and has some good advice then let me know please .. or some cheats (that work) that would help too ;)

The game seems to be hard but it´s quite easy once you master it. Although that doesn´t tend to happen on the first playthrough (specially on levels like you say, where you are surrounded).

First, you must try to get your creatures training, researching and building traps as fast as you can. Try to look here and there because you will recieve new creatures and you must put them on work as fast as you can. You must do everything you can as fast as you can.

You should also get the imps to the "secret path" (that obvious one surrounded by unbreakable rocks that has a door and a killing rock on it), and to the water. Both paths have special items to raise the level of all your creatures, so they can be devastating used well.

Don´t ever open your locked doors, and don´t put the worse traps, so you keep constructing the good ones. Use the good traps right before a door, and keep putting doors where the heroes get to destroy the last ones. When the heroes get to the last door to your lair, use your creatures to kill them all. Pick all the money and put it on your treasure room, or it will be payday and your creatures will leave you.

It´s all a matter on when you do things more than everything. The raise level items are the key for the victory too ;)

OK, I just finished this one yesterday. Not too ahrd when you know how.
First attack will come from the left. Hopefully you have been combing the dungeons for the xfer creature special, as my Mistress held 2-3 legs of all attacks solo until late in second phase. If not, you are in for a harder fight.

Get imps claiming territory, and get some Trolls/BDs manufacturing. Also get your spell research up ASAP, as the chicken spell is a HUGE help late in phase 2.

As soon as an enemy shows up, zerg them. Once they are down. start with traps in the hallway in, and always keep the door going to your dungeons locked. Unlock them ONLY for mining and claiming, until you have yourself established.

Once you take the circular area on the side, I start with left, i put some traps right where they spawn at. Later on it wont stop them, but when you get the 2 level 6 Faries popping there about 30ish minutes in, they are both at half HP and alot easier to take out.

Watch the order and where they are coming from. As soon as an attack there is done, get your imps mining there and prep for the next attack. 2 gas bombs and 2 lightenings at the spawn point does wonders for your survival. The lord of the land comes from the right iirc.

I have found that this mision, much like the Siege from Lord Asmodius in Dungeon Keeper 2 (7th mission iirc, maybe 9th... the one with the 45 minute countdown until you get charged) are best handled if you use traps at spawn/choke points, and get out there and be aggressive.

After about 4ish attacks from each side. You assistant tells you basically you get a break and harder guys are coming. Train up as fast as you can. Make sure you have the area thoroughly mined with traps AND your spells are done.

Late 2nd phase, you will start getting monsters level 6-9. When you have multiple mobs coming, chicken th highest one, unless ou are confident in taking them down with little to know damage taken.
--Always remember, use the armor spell when in tough fights, and the speed increase can be a definite help as well, and they are both CHEAP.

Just keep a cool head, get your monsters back healing, keep your strongest ready to be dropped at a moments notice, and if you are good on money, use the heal spell on them, keep them at 100% My choice was my lvl 10 Mistress, others have kept their Bile Demon, Dragon or Vampires. It all what you got, and what you like using. Dont pick a Mistress because I recommended it, pick her becuase you like her and do some damage with her. If your style is best with a Warlock, then grab a Warlock.

Basically this map is not very hard, as far as the battles themselves go. It is a endurance round, and one that forces you to keep calm and a clear head. You lose your cool, they will be all over your heart in no time.

99% of this game falls into the "Easy when you know how" catagory. The mission that was brutal was the last one, the fight with the avatar OMG..... he took down like 3 reapers, a wall of mistresses, Bile Demons and Dragons, all LVL10, and he did it by himself. Haven't gotten back there yet.... gettin there though, I just remember it vividly in the 90's.

There´s a nice strategy for the last level you should try if you didn´t back in the time. Once you reach the avatar, you can put him in jail, then torture him, and then it will be in your minions. That will spawn the second avatar (which will spawn next to your dungeon). Heal the first one and watch them fight :)

You can always help him with your magic, use traps too for the other one, use all your minions to fight him...

Disease really damages him too :P
