Quick version: You only need to beat 1-10, 2,-10, 3-10, 4-10 and die once to earn all the achievements. (you must also save the hostages)

You can either start a new game or use an existing file.
If you're using the R-18 patch, you'll need to reinstall the game to earn achievements. (Your save won't be deleted)
Cheats DO NOT disable achievements.

Once in the cell, hit tilde (~) to open the console. We're going to use the following commands:

gotexp 100000 - This will make you maximum level.
givemoney 100000 (Optional) - This will give you way more money than needed to buy all the costumes.
tef 1 1 1 (Optional) - This will set your three family members as "saved" for the true ending.
cas - This will unlock all levels and reload the cell, making all of the above changes take effect.

Now let's play.

It's time to beat the stages. Cinderella walks through the cell really slow, so we're going to cheat for that too.

Let's use this command:
ll Stage-01-10 - This will warp us into Stage 1-10. Beat this stage to unlock Escape Newbie. (1/8)

ll = LL, just an fyi.
Return to the cell.

Use the next commands in order, after clearing the stage and returning to the cell:

ll Stage-02-10 - This will warp us into Stage 2-10. Save Mercy and beat this stage to unlock Saved Mercy (2/8)

ll Stage-03-10 - This will warp us into Stage 3-10. Save Venia and beat this stage to unlock Saved Venia (3/8) AND Escape Export(4/8).

ll Stage-04-10 - This will warp us into Stage 4-10. Save your step mom and beat this stage to unlock Saved Step-Mother (5/8) AND Goddess of Escape(6/8) AND!! True Ending (7/8).

You'll be back in the main menu now. For the last achievement, you simply need to die. If you didn't die in any of the above stages, just visit a stage with a trap and intentionally suicide to unlock Escape Artist (8/8).


That's it! How do you beat the stages, you ask? They're not hard, so figure it out yourself.
Here's a couple of hints:
Stage 2-10: You need to be pingponged into the corner by the first swinging axe.
Stage 4-10: You can skip the second half of the map entirely, just climb up the tower in the middle.

Shouldn't take longer than 30 minutes to get all the achievements. Good job, you worked really hard!
