How to unlock ZIP achievement?

[thereisnofuture]

So Ive completed the run in under 20 minutes (beat ???) but nothing happened is there any special conditions for this achievement? Its annoying af to speedrunning on hard mode.

I did it with the Lost on my first or second try - I recommend him (if you have Holy Mantle unlocked), because he comes with free Deals with the Devil. You just need a fairly good first item room and you're good to go. Sure, it comes with a bit of luck as well, but if you can dodge well enough, you are fine.

I unlocked "Zip!" together with "It's the Key" on the same run. Ignoring everything really speeds up the gameplay.

There's a bug with Victory Lap mode where, if you close and open the game while in a Victory Lap, all achievements and unlockables will be enabled, allowing you to get easy achievements as you plow through the game with an overpowered build. I used this tactic to get ZIP!, and I was able to beat The Lamb in exactly 5 minutes. Trust me, it works. (Just keep in mind that you're still probably going to need the Sacrifice Room tactic as well.)

Yeah, but you can just finish a run, by defeating the Lamb (doesent matter which time) and do a Victory Run. This will count as well.

Come again?! I came in with just a few seonds over 20 minutes in hard mode and just couldn't figure out for the life of me how to complete this achievement without making a ritual sacrifice to the RNG gods. Well, I guess my cat lives for another day.

For the guy that probably come here as a desperate attempt. The BEST character for complete this achievement is TAINTED MARGDALENE.

Just made this achievement along with "It's the key" with Lost. Collected only keys for treasure rooms and went straight to the boss. Got to Lamb by about 15 minutes.
