Favorite dead game modes?

Gotta say my favorite dead gamemodes have got to be:
1: Sleedbuild (I actually don't remember the name, that's just what my brain thinks of): It was a gamemode where a bunch of people would build a sled to race to the end of the track.
2: Gmod Stranded: A survival gamemode that made use of tribes / hunger thirst and fatigue / resource management to make a general fun experience.
3: shh I've only played a handful of gamemodes get off my case qwq.
