Some Runs such as the introduction campaign run uses units from other factions. but in the current version of the game you can no longer use any factions on some levels except tribe making the run much slower. What do we do?

I'm not sure if that's the case - I've just looked into it (I haven't played the game in a week or so, so I was concerned) but I can still use all units on all campaigns. Be sure to check you have "All units enabled in campaign missions" checked in the Gameplay tab of settings!

Ah, I see. Thanks a lot! Didn't know it was a thing

Speaking of outdated runs, the Full Game category needs to account for for Wild West and other future campaign levels. The current WR ends at Spooky, which is inaccurate.

Damn you're right, I'm going to think about a way to fix this

So what would people think about a series of sub-categories attached to the full game category which add on new campaigns as they're released? A similar fix has been implemented here: https://www.speedrun.com/dragon_escape/full_game
