If you've managed to talk 3 friends into getting this with you, you're gonna have a great time.
Though co-op isn't exactly required to play this, anything above Haz 4 because a little difficult for solo play, or even duos.
Should you be looking for a nice game to chill out in, though, I think this is a pretty good fit.

Despite being made mostly out of randomly generated levels, it takes quite a while for each cave to start looking repeditive. There's a good amount of variety in between biomes, from a barren wasteland with crystals you probably shouldn't hug, up to beautiful night-blue grasslands. The game will usually give you quests in a variety of these- I've rarly had the same biome be repeated over the course of an entire questline.

The gameplay is really strait forward and mostly intuitive; You've got your four classes to pick from, each one fitting into a specific role, but all of them being very open to different playstyles. The classes complement each other, so if you're in 4 player co-op, I can personally recommend getting a different class for every player.

Customisation is varied and quite in-depth. I've never really had an eye for customisation, other than showing off what I had, but if you're into the near-skyrim level of character customisation- well I guess you've got a good pick here, too.

This game also has one of the most detailed and well-crafted lobbies I've ever seen. There's quite a bit to explore and a few minigames, should you be waiting for other players to return/join/etcetera.

For downsides; Some of the missions are quite repeditive and due to the rng-levels, you can sometimes spent hours in a mission trying to find the last 7 ♥♥♥♥♥♥♥♥ morkite (speaking from experience...)
There's also several small clipping and texture issues in level geometry in the lobby, but hey, if you don't have an eye for that it wont ever bother you, and this is already a pretty nitpicky point.

Overall, it's a solid game, and even if it's not on sale, it's been worth every cent to me (which goes as far as that I bought this game twice, in fact).

10/10 Must have
