Take and Hold is the only one I found fun for any significant amount of time. Lots of weapons suits the RNG. You should mod more maps and characters (spawnlists) in.
Shooting ranges are shooting ranges.
The zombie one is a campaign with a story but it's not exciting.
Wild west theme park is just minigames and walking around. Gets old very fast.
There's a horror one with a maze and 'puzzles'. Never bothered to complete it.
A Christmas arena has a few different modes, one is an alright wave defense with a tedious score mechanic.
TF2 mode. Some people seem to like this. It's an infinite team deathmatch, meh.

Probably another few shitty modes I forgot, unfortunately it's a disjointed collection of whatever the developer wanted to work on at the time.
