Talk:Boss Rush

reset bug doesn't work in afterbirth
Bugs should probably be marked with a persistence layer if they aren't present in every expansion through Afterbirth+

As I found out, the "exit game as soon as you get an item" bug doesn't exist in Afterbirth, so it should probably be marked with the struck-through DLC indicator.

Only 2 items in Afterbirth
I was playing a normal run as Lilith and when I got to the Boss Rush there was only 2 items, is this normal in Afterbirth? I haven't been able to get to the boss rush again so I can't check right now. --Anon

Yes, this is one of the new possible rooms. --Zamie (talk) 02:38, 10 December 2015 (UTC)

Possibility of 3+ items
I've encountered a strange case where a skull broke when I entered the room, which spawned a Host. When I beat the Host, the room was considered defeated. The achievement for the current character to beat the boss rush room was unlocked, and the normal winning item drop was placed in the center of the 4 initial item choices. Picking any of the 5 items will start the boss battle, like normal (even the item that was in the center). When you defeat the boss battle, a 3rd item will be dropped in the same place as the winning drop location.

I played as Eve on PC seed QHPK EREJ. When I beat the Host, I unlocked Eve's Mascara. The floor was in a Curse of the Unknown, but I picked up these items in order: Flush! (the center item, started the boss battle), Cricket's Head (bottom left item, other three items disappear, like normal), and Rosary (second center item, after defeating the battle).--Televis10n (talk) 21:40, 7 December 2014 (UTC)

This sounds highly interesting. I'm on my way to test this and will report back asap. --Dooomspeaker (talk) 22:06, 7 December 2014 (UTC)

Couldn't get the skull to break on it's own, so I eventually broke it by bombing and then killed the host, which did nothing for me. I'd suggest putting it under the bugs section together with the seed and add (needs another confirmation) to it

Can confirm that this bug exists. Played on seed KSHS 9YHG as Judas on PC. When I entered the room, a Host appeared. I killed it and then a fifth item showed up (see picture).

This bug should no longer be possible since the memory leak is fixed now in the latest version of AB+. --Zamie (talk) 08:52, 22 January 2017 (UTC)

Carrion Queen
I've been playing the Boss Rush quite a lot over the past couple of weeks to unlock items. I've noticed that the Carrion Queen seems more often than not to spawn in its Champion version, with the Infamy-style hearts. Which is great because it doesn't drop the red poop that gets in the way for the rest of the rush. I think it's only spawned the normal version something like 2-3 times out of 12-15 runs. Has anyone else noticed this?

If you do the Boss Rush without unlocking 'Everything's Terrible!' does that always cause the normal annoying Carrion Queen to spawn? --77.102.114.99 23:30, 12 January 2015 (UTC)

Beware of The Golden Chest
This is probably because Boss Rush rooms are pretty much similar to Challenge rooms, if you opened a golden chest found in the rocks while not picking any of the pedestal items, the Rush will commence.

The seed is SVWT HLQE as Hard Mode Judas. --ZeroTheEro (talk) 00:22, 1 April 2015 (UTC)--ZeroTheEro (talk) 00:22, 1 April 2015 (UTC)

Afterbirth+
Something strange happened when i cleared the fight against the last wave (that one that open the deals room) on greedier mode with apollyon. A boss rush/hush-like gate opened instead in the last level before ulta greed and the greedier, by my stupidity i didnt enter nor screenshot. Here is my seed: NNWK GMCY

Hour ignored?
If you play for over an hour, it seems to reset your clock? So playing for over an hour, but if your minutes are within 20, it seems to trigger Boss Rush. --Dwedit (talk) 19:38, 11 July 2020 (UTC)
 * I strongly doubt this is the case without some kind of picture/video proof. The game internally stores the time as frames since start (at 30 frames per second), and the time goals are set as frame counts as well as per the modding API. At no point are actual seconds, minutes or hours used. -Frionil (talk) 19:47, 11 July 2020 (UTC)

That's very strange then that I managed to trigger Boss Rush with a time of 1 Hour and 19 minutes then...--Dwedit (talk) 20:07, 11 July 2020 (UTC)
 * Mama mega lets you ignore the time limit. -Frionil (talk) 20:42, 11 July 2020 (UTC)
 * Didn't know that about Mama Mega, thanks! --Dwedit (talk) 00:26, 12 July 2020 (UTC)
