Looking for some fun gamemodes.

Hey, as the title says: I’m looking for some nice fun gamemodes, that take kind of long but are pretty good to play.
Something like Elevator:Source.
Preferably Singleplayer!
Thanks in advance!

There aren’t really many gamemodes for 1 person, unless you like building you can do that in singplayer, but that’s not really a gamemode.
