The subcategories of Original Campaigns that were on the main L4D2 leaderboard (Solo, Co-Op, and their expert realism variants) have moved to this leaderboard. This was meant to be done many months ago, but the time and motivation simply didn't exist to make it happen. Unfortunately, due to limitations of speedrun.com and how the category extensions board is laid out, this does mean we lost the players variable (the variable used to filter co-op runs for 2P/3P/4P), and overall, the way the subcategories look on the board is a bit ugly, but it is what it is.

If you have any questions, feel free to ask in the speedrunning Discord.

Hey everyone, some minor changes to the rules - solely to clarify things/change wording, no rules actually "changed" (at least not in any way that will be relevant to 99.9% of people):

• The linked guide for demo recording is now in a new location on the internet ( 👀 ) and was reworked to hopefully be clearer/simpler/etc.
• In an attempt to make things clearer for new people, it is now explained in the rules that loading into the first level of the campaign, pausing the game, and starting the demo recording would result in an invalid run if you completed that exact attempt without restarting (because the demo doesn't contain the entire intro cutscene if you do this)
• We have now clarified that you can only play campaigns that are a part of the category/IL you are running (as was concluded in discussions surrounding Original Campaigns)

If you have any questions, please ask in the Discord server

We've updated the Keybinds/Commands section of the rules to be (hopefully) clearer about what "tricks that require the developer console" means. We believed that the way it was worded previously was contradictory with some commands present in the whitelist, which could lead to some confusion. No rule is meant to be altered by the updated wording.

Hello everyone,

Original Campaigns has finally been added as a miscellaneous category on the main L4D2 board, and a corresponding entry was created on category extensions. Based off of community feedback, the solo infinite votes subcategory was added to category extensions - in order to run this you'll need a custom build of SST which can be downloaded here. With this build of SST, you can change sv_vote_creation_timer without enabling cheats - the only legal value for this category is 0. It goes without saying that we can easily tell if you attempt to use this elsewhere.

Additionally, if the standard Original Campaigns category on the main board turns out to be completely dead with no interest in a couple of months, then we will transfer any existing runs to category extensions, so there should be no concern of being stuck with a dead/unwanted category on the main board, even if it's hidden behind the misc dropdown.

Enjoy!

Hello everyone,

Going forward, we will make a concerted effort to announce every leaderboard change both on the Discord server and in news posts like this one on speedrun.com, regardless of the significance of the change. In the past, we have been inconsistent in posting important rule changes on speedrun.com, which is an issue, because some of these changes were only known to those in the Discord server or those who meticulously read the rules every few weeks, which isn't exactly reasonable. The leaderboard changelog thread (although currently accurate/complete) has also been updated very infrequently in the past, which hasn't helped either.

From now on, all future updates will be made in news posts (as well as announced in the Discord server as usual), and the leaderboard changelog thread will now be retired.

If you aren't in the Discord server and thus don't know about some of the more recent changes, we suggest you read the changelog thread or reread the rules to be safe.
