If you do the same with walls or props, the trooper will pass through them.

Is it necessary to give the opportunity to complete each campaign with all possible difficulty levels?

If this is not the case, then instead of choosing difficulty, this can be done by choosing a speedrun category: any% (at least somehow), any% max difficulty, 100% (all difficulty levels? does this include completing the campaign in all ways?), ...

If this is the case, then this can be done with difficulty levels as sub-levels of the level, such as speedrun some level of the world in New Super Mario Bros. Wii.

If there was a mod that allowed to edit the randomness of enemy spawns without editing the map itself, would it be allowed for speedruns?

I made a short video where I showed 2 methods for reproducing this bug.

Also there are 2(?) more method, but I don’t know how to reproduce it. They all involve using a second partner.

1. Partner dies when he should have opened the door (video moment). But when I tried to do it myself, nothing worked. The remaining operative simply broke down the door.
2. Something to do with your partner (look this and this runs). I don't know what's going on here to reproduce it. Maybe this is a repeat of the second method, but with the obligation to break down the door after illegal entry.

I'm scared to look at the abbreviations of campaign names. Is it possible to make campaigns as separate "SRC" levels? For example, check out the No More Room in Hell and Left 4 Dead 2 speedrun pages.

While reviewing the replays I noticed another invalid run (Campaign lost): 1.11.

You can achieve the mission using a bug with replays. But getting each of these replays will take time... or download from somewhere.

If were unable to complete the mission as required and somehow did not press “restart”, then the opportunity to restart the mission will not disappear if person haven’t progressed anywhere further along the campaign mission branch.

Or perhaps make a mod that adds each of the campaign missions as a separate single missions.

Continuing the topic of the thread, the following run do not follow the rules and should be removed: 1.7.

And about runs 1.14, 2.2, 3.2 and 4.2. Is it allowed to do this?

I want to speedrun individual levels of campaign. How should I submit my run?

What needs to be done to update the rules?

Moderator's wording is exactly according to the rules for speedrun the full campaign:

... Time ends upon score screen of the last level (Mission Completed).

And it cannot be otherwise.

Thus, other runs don't follow this rule, ending the last level as a failure, and should be removed.

Based on the moderator's decision the following runs are invalid and should be removed:
