Hey Zeref,
In 2022 Category extensions were brought from the Category Extension pages here on Speedrun.com to Haloruns.com.
We've recently renamed and rebanded this page to focus on content that is not already covered by Haloruns.com, so that there is no overlap. This included archiving the old categories, which were largely inactive and abandoned anyway.
Also, you might be pleased to know we have a new, 2-Player specific category now so that you can stack your run up against other duos. (You'll be able to submit to the main Co-op category as well.)
Let me know if you have any other questions
There are multiple places you can stand in Lone Wolf where the enemies will not aggro you whatsoever, so the category would come down to who wants to leave their machine running the longest. Additionally, surviving for the longest time does not fit with the concept of a speedrun.
