    *This Achievement Should no longer be glitched if you've beaten boss Rush before the patch just start a new run and your achievement will unlock*

    Time for the guide.

    To get to Boss Rush, You must defeat mom in under 20 minuets. When you do that a hole in the wall will appear, go inside it. You will see 4 items always random; when you pick one up the boss rush begins. The boss rush has every boss you can fight in the game up-til the mom fight. once you beat the last boss,another Item will drop and you have beaten the Boss Rush Congratulations.

    I recommend using azazel as he starts out flying and does the most damage at the start of the game. you also just have to play fast, just find the Item room and fight the boss. It's all luck of the draw on what items you get, you just have to have luck. The best Item to have is the or stopwatch (unlocks after donating 999 coins to shop) as it slows down enemies in every room; Making it easier to clear rooms fast.

    AwooYup, definitely glitched.

    Ramon99108Neither the broken stopwatch or the regular stopwatch slows down the timer. They only affect enemies and their bullets.

    AwooHe never claimed otherwise. The Broken Stopwatch is an AWFUL item for this though, as it also has a chance to speed up all enemies in a room. I had a run to the Hard Boss Rush with The Lost once where the entire boss rush army was sped up significantly, and while I somehow almost beat it, it was absolutely ridiculous.

    SuperSonicDeluxRamon99108 Solution has been edited, I must have been thinking of a different game that slows down the timer when you get a stopwatch.

    Ramon99108That is fine, just trying to help out new players to the game.

    The9thChevronBy far the hardest pair (for me at least) is The Bloat + The Mask of Infamy. The Bloat can snipe you from offscreen and The Mask of Infamy can come flying out of nowhere.

    AwooYes, Bloat killed many of my Lost runs on Steam for that exact reason :P

    Dreadful DadI stumbled upon the boss rush yesterday with azazil. Had about 8 hearts barely survived it and was like what there is no achievement for this!?!??? Turns out it's glitched. Hopefully it pops eventually

    JayowskiI can confirm this and The Womb is glitched as I recently completed both and got nothing :x

    KEYMAKER99They are both glitched, but the Womb achievement is still capable of being unlocked. You just need to do "The Mind" achievement. Do that and you will unlock both. Sadly, all we can do for this achievement is wait for a patch.
