There are SPOILERS. Don't read if you don't want any spoilers.

There are - 3 - paths. Each path is basically independent from the others. If you don't want to fight, for example, you can still have fun with the girls or searching ITEMs. (except for one room near the elevator which, I think, is the easiest one.) If you don't want to search the item for the Operbots, well, you're missing out on a treat but otherwise it doesn't matter for the ending. And even if you don't find all girls you can still get the Happy End.


If you get stuck fighting bad guys try to get in from the other side.

But how? There are hints that should lead you to big ventilators. They can be opened with a crowbar or ice pick, behind you find a tunnel or door. Both Depot and Reactor can be reached through these tunnels. Lure the bad guys to one side, than pick them up from the other side.

You can also get a better gun or find a stash of mines and medkits.

Bad Guys usually have a keycard so they are worth fighting.

If you fight the guys in Reactor you get a keycard that will help you find the Red Rifle which helps you with the good ending (but that's not all you need...)

Good ending? Happily ever after? Sure! You need to eliminate all creepers. You can shoot them but they respawn in Hangar. What keeps them alive...? have you talked to Shansky? Look at his monitor, too.

Actually, entromutation spiked to levels unseen before. How do you stop that? Cut the power. How do I do that? shut down Anchor in the reactor. It can be turned on an off now.


What's with the girls? Find them and bring them to the shuttle.

How many are there? You'll know when you have them all.

Why do some girls not go to the shuttle? They are either dead (incinerator) or have a robot brain (the former cell girls)

Is Shansky alive? It seems he is stronger than the others. Genetic defect, bitten by a spider, who knows...


There are items you need to use on the Operbot: ice picks or swords

Where are those items? There is 1 in blue and 1 in orange and 2 in Technical.
Additional hint: They are in rather big rooms
More hints: In one room you need to fight, in another you need to climb, in one you need to search in the last corner, and in one you need to do a run-around.
Note, you don't need to find all 4, since you can also use the swords.

How do I open the inner doors to the center? disable all 4 OperBots
Where are those OperBots? at the 4 entries to (former) Admin.

Anything I need to find in the White Area? there is one reminiscence to HD1 (one of the first achievements you got there...) but basically, no, just discover the center area.

Where are the swords? They are exactly where they are in the main game. How many? there are 3 swords

So I can actually use the katana? Exactly! :)


What is your problem with Admin? I really wanted to have Admin explode and open a path to hell but that would've been too difficult.
Who reconstructed Admin? Let's blame it on Shansky, entromutation, and a delirious mind.
Tunnels: Is there a reason? Tunnels allow you to attack bad guys from the other side.
There's is one ambush panel you can enter? It's supposed to be a hint that there is something else in that room. I always wondered where all the doors in those ambush panels lead to...
Shouldn't the door of ADM_Trial point WEST? You, sir, have a fine sense of spatial orientation but no, that area (not on the map) is warped by 180°. Depends on from which side you go there. Which is why I think it well deserves its place at the center of this twisted game.


And finally, this is the sketch I used when making the mod. It reveals everything.

Feel free to ask here if you have any other questions and I'll try to give more specific hints!
