"still doesn't have one right version for speedruns like a hl or portal?"

HL has had a few different versions be used for speedrunning over the years, even in the last few years people have been using different releases of the various pre-steam versions of the game for different reasons. You could also make the same argument for that game that people should use the steam version, but no-one really does because of the bhop speed cap and overall being a worse version to run.

As others have said every official version is valid, you can't force people to use the one "correct version". And really, its a speedrun, the correct version is always whichever is known to be fastest at the time. There's still literally nothing stopping people from running any version they want, including newest.

How will new players be attracted by seeing less interesting with fewer skips? Besides there's not really that much difference between versions that you will notice when watching or playing them, and you can easily find them in the discord.

Leaderboard for LMOE got removed some time ago, sorry.

Basically, LMOE but on newest. And expert realism if you wanted it to be any slower.

But really if you want to decide what's allowed and what isn't I think you would have to do it by categorising them and not individually limiting each glitch otherwise it becomes too arbitrary, e.g. movement instead of bhops

As Master said, there's nothing in L4D2 that is really game changing demands disallowing because it changes the game entirely. It's already not actually that different than playing normally.

Use an autoshotgun, it melts tanks in L4D1

Good luck getting into the saferooms.

Dead Air 4 has 2 back-to-back events with common spawning in front all the time, which can't be skipped.

The current Dead Air route is currently all on expert. It's not that big of a deal, you shouldn't be getting hit in the first place anyway even on easy and most of the events aren't a problem if you do them properly.

Time to do all runs on expert to show off OSsloth

We used to have a separate easy and expert category for LMOE and it made basically no difference, actually.

I don't think we should really have any more categories lol, we already have enough that make the leaderboards confusing and messy enough to look at, especially for anyone new. The difficulty change doesn't really add much or change much about the route or strategies in this game unlike something like HL1 or Halo, it just means you die faster if you get hit by things mostly and can do slightly less things. Whatever the current difficulty we run is should be called any%/any.

Why not both OSsloth

3, 2, 1 looks best, easier to tell what it is at a glance.

mat_hdr_level is not sv_cheats protected, but it is a "hidden command" and is still protected in multiplayer source engine games: To use this command in the console I used a plugin that gives access to all hidden commands. But you can circumvent this by exploiting a flaw with launch options, it's by no means an "intended" launch option.

My plan is to find so many good maps that you have to make an All Campaigns version of this OSsloth

Death Row: http://www.gamemaps.com/details/2227 / http://steamcommunity.com/sharedfiles/filedetails/?id=121971655 +promising coop and solo skips +can skip most of map 1 easily -some missing textures, especially in later maps (for me at least) -seems to be lacking in some items (adrenaline, bile, grenade launcher) Worth trying

Blood Tracks: http://www.gamemaps.com/details/2750 / http://steamcommunity.com/workshop/filedetails/?id=377195503 +easy finale jesus spot +some pretty big and easy skips on maps 1 and 2 +open maps, good for bhopping -static tank map 3 May not be great, but has potential for runs

Bad: Carnage 2 Death Strip Death Stop Road To Nowhere 2 The Last Volt - Weird map, has potential for skips though Heaven Can Wait 2/Hard Version 25 To Life - Too boring/not enough skips Dead Getaway - Promising skip potential on map 1, but the rest of the maps are unspeedrunnable Deadly Dispatch Dead On Time 2 Dead High School

Been testing out some other maps not included in this thread, here's what I have so far, I still have a lot more I want to test.

Carried Off: http://www.gamemaps.com/details/2230 +potential for coop skips +bunch of smaller tricks +open maps, good for bhopping +really long event on map 3 is skippable very easily in both coop and solo -maps seem kinda long -finale is very difficult ~4 maps ~running finale Definitely worth checking out.

Death Sentence: http://www.gamemaps.com/details/2624 +good potential for coop skips +decent map length +starting the event on finale can be easily skipped in solo and coop -lacking in solo skips -map 3 has crash potential -scavenge finale is very big/open ~scavenge finale Could be good to run.

Drop Dead Gorges: http://www.gamemaps.com/details/2135 An interesting map, it only has 3 maps but they are all quite long. The maps are unique as they focus on giving many options for diverging/alternate paths, giving plenty of potential for skips and good route optimisation. Has some potential for skips from what I saw, especially in coop May not be the best campaign to use, but is definitely worth checking out.

Highway To Hell: http://www.gamemaps.com/details/2714 +some potential for coop skips +good bhopping +resonable map length ~holdout finale This one is a maybe.

Blood Proof: http://www.gamemaps.com/details/3994 +well made map +event skip map 1 (easy in coop, harder but possible in solo) +finale event should be skippable with grenade launcher ~3 maps, each somewhat long -possibly lacking in skips ~gauntlet finale This one is a maybe.

Other maps I tried but were bad, mostly just too long maps/lack skips/just not fun: Day Break 2 - These maps are far, far too long Dead Vacation Dam it 2! The Director's Cut - Not suitable for speedrunning Deadbeat Escape Fall In Death One 4 Nine - A few skips but maps are too long Blackout Basement

Centro: http://www.gamemaps.com/details/2368 3 maps Almost thought map 1 was unbeatable but it is just badly designed. Probably not that good to run, but has some potential for skips.

Cold Case: The Forsaken: http://www.gamemaps.com/details/7118 Map is poorly made (doesn't even have lighting), doesnt feel like l4d2 map. Seems to have some skips but didn't bother testing past map 1.

Special mentions have to go to Black City Extended This map pretty much does not use clipbrushes in the first few maps, so you can do what you want (I counted 5) 7 maps, 2 (or 3) of the maps are literally stolen from another custom campaign. Have no idea how to start the finale (cant press the radio), but it appears to be a scavenge finale in sewers with water slowdown.

I just personally prefer to not use the workshop, you can't stop the map from autoupdating if it ever gets changed if you use the workshop. It's not that much harder to download the file from gamemaps.com as it is to subscribe on the workshop. But yeah it doesn't really matter that much I guess. OSsloth

Top 5 maps I would recommend considering are: Diescraper Redux Detour Ahead Arena of the Dead 2 Open Road Haunted Forest

Though I haven't played any of the HL2 maps, so they might be decent too, but the 5 maps above are all pretty good quality.

Here's some more lists: http://sirftp.com/Left4Dead2/Custom%20Campaigns/ https://www.l4dnation.com/mapping-discussion/complete-list-of-every-custom-campaign-in-l4d2/ https://www.l4dnation.com/mapping-discussion/the-best-custom-campaigns-for-competitive-l4d2/

There was one before for coop runs but noone uses it anymore I think.

2.0.0.8 won't work on linux, compatibility for linux was only added much later.
