1. Record? sure though I'd recommend obs myself. Submit? No. All run's must either be submitted through youtube or as a twitch clip.
2. Run's can be on whatever difficulty you prefer, though often there is an optimal difficulty. What difficulty you may ask? well that depends on the run, generally though if your killing enemies you should probably go violent. If your not killing anything or killing very few things, then harmless. But again, depends what your running.
3. Rank does not matter unless your submitting to P% as obviously it'd need to be a P-Rank to submit to those boards, otherwise if your submitting a run to Any% the rank does not matter.
4. The start door will open quicker to accommodate for higher speeds such as slam storage, but other methods of speed such as an ultraboost will require you to wait for the door to open first. Generally the door starts to open once you walk down the steps.
5. The poll will close when the next update comes out, which based on what I've been hearing will either be late this month or early next month.

We do not take text suggestions for categories here, if you want to you can wait for the discord to come back up and bring this up there. However I will say people have already ran something similar but under a name that actually makes sense and grabs all 4 skulls aka "All skulls" there's likely been runs for just the skull door as well likely called "3 skulls", "skull door" or "no challenges" runs or something of that nature. Anyway all this to say this hasn't ever really become prevalent enough to become a category for us to host at least not currently.

Currently it's down, It'll be off for a little while but it wont be permanent. It will be back up in an undetermined amount of time, apologies you might not be able to join for a bit.

We do not take text suggestions for categories here for everyone's info and as already mentioned weaponless already exists. Also no-damage runs have been asked for before and even ran but they are considered more so challenge runs, especially for fullgame/multi-level runs and so will not be hosted here. If your curious about how a category could get added, then read this.

Ultrakill is not available on any consoles other than I guess a steam deck, which I'm not sure if they could down patch but I wouldn't be surprised. In terms of differing category for patch locked runs that has been discussed to death and generally the answer is no at least not until the game is out of early access since it'd take a lot of time and effort to add something like that now only for a potential future patch to come out and have something else break speedrunning anyway. As well as the whole board being wiped when we get to full release anyway. For now the best we got is tagging runs with the patch they were on, so if you really don't care for downpatching and want to know what the fastest run of 1-4 without old patch weapon wheel is then go to 1-4, go to filters and specify each patch after EA (8/16/22) [The last patch containing old weapon wheel] and you'll get runs without old patch weapon wheel.

The weapon wheel seen in 1-4 wr was from an older version of the game when it would slow down the timer as well as the gameplay. If you want to use that weapon wheel now then your only option is to down patch.

The problem is determining what counts as a "glitch" and what a "glitchless run" would look like in ultrakill. Would you count slam storage as a glitch? How about dash extensions? What about ultraboosting? Dash slide jumping? Super slide jumps? and the list just goes on and on. There's quite a bit in ultrakill that was maybe at first unintentional that becomes just a part of the game, so right now inbounds is what is usually settled on for anyone looking for a "glitchless" run experience and sometimes that's really all someone is looking for when they mean "glitchless". Also yes at some point in the future we plan on adding weaponless and inbounds IL boards, as for when I do not know.

It has now been added back, will likely not stay forever as we have other reasons for changing the link and taking it off site that I'm not going to divulge here. If its ever not there then It wasn't removed for no reason nor was the discord deleted and will likely be added back in future after some time whenever it happens again.

Depends on the run, only top 10 runs Require audio so if you need to, yes you can remove the audio. In future though I'd recommend just recording the game audio.

may wanna add some level leaderboards, but it should be updated on steam not sure why its not for you though?

If people ran it, this could be something later down the line potentially, but likely not for a long while considering most do not run it and we already have a lot going on with IL's anyhow.

No, if anything it could be a contingency like 4-S has with "Any Boxes", "All Boxes" and "78 Boxes" but unless people run it I don't really think it'd become a thing, not to mention it'd basically be the same as Normal Any% anyway because of the Clip. The only difference would be if one of them or both of them were inbounds exclusively and we already plan on having inbounds tag's for IL's later down the line.

Well again, we don't allow mods ever so this would be out of pocket for us but unless the bugs are fixed in the mod I don't think it'd really matter but not like I play the mod anyway and as I said, we don't take text suggestions for categories here. Get others interested in running it, and have runs out there and then we can maybe have a discussion about it.

It is still possible, though I don't know or remember the best way to go about it but for your info the P-2 OOBs clip seen in P-2 Any% wr or the following runs do still use a clip that works on current patch. What I did to get the style bonus was grab the invisible checkpoint infront of quad cerb room, then go back and use the intended skip to sisyphus, shoot the glass to load the room and scrongbongled kill zone then checkpoint load to the quad cerb room, do the clip, activate first mindflayer arena from OOB's, checkpoint load, do clip again, and head over to the spot and hope mindflayer dies. Don't know if this is the fastest method, but its what I came up with on the spot so feel free to mess around with it.

Any difficulty counts, we don't separate boards based on difficulty. (yet, supposedly this is going to be changed later down the line but not right now.)

Anyone can run any difficulty they want, however if we're talking optimal difficulties it depends on the level, the category and or the enemies. Standard and Lenient specifically are almost never used since they are more of a bridge between violent and harmless and don't really offer any unique benefits. Harmless is always faster if there's no enemies to kill or very few as well as being good on some boss levels thanks to more health and faster stamina regen. (Also its basically THE option for NoMo or NoMoW runs) Violent is usually always faster if you have to do an arena fight that you can't clear in less than a second and depending on the enemies can be better than Brutal due to some changes made to make it harder. Brutal is a bit more situationally faster as a few enemies attack speed and movement speed is increased but some enemies also get changed so they are harder to kill for example mindflayers don't take damage from their projectiles anymore so you can't do the standard instakill method and you can't bait out a guttertank parry (unless you spray gasoline under them first) which could lead to a faster kill in some cases as well as boss fights being objectively slower on brutal because of the health increase. All this to say optimal difficulty is highly dependent on the level, the category and the enemies you are fighting.

Depending on the run your watching, there's a very high likely hood any rocket clips you see in level runs are patch locked.

At the moment you can run whatever difficulty you see fit, however the most optimal difficulties will always be harmless (For when there are no enemies or at least very few) or violent (when you have an arena or multiple arena's to clear) We plan on adding something for other difficulties later down the line, most likely when we get to 1.0 (Full game release)

That 6-1 clip was patched, you'll have to downpatch if you want to do it in a run.

No, although we will tend to verify level runs sooner than multi-level runs primarily because multi-level runs just take longer but we don't verify higher placement runs sooner just because of higher placement, we go in order of submission date.
