I picked this up at launch last year and played a fair bit with a couple of mates. We stopped playing for two reasons: the skill cap is reasonably high, so we started getting beaten by young whippersnappers on their PCs. And while you can disable x-play, it makes it harder to get a game.
The second reason was while I don't think it was related, the matchmaking seemed to break a bit after one of the patches, and a lot lobbies seemed to have a high bot count thereafter. Game Pass might give it a nice boost (if it's even still a problem; might not be).
All that said, I really enjoyed it, and keep meaning to go back.
- Don't take it too seriously. There's loads of fun to be had, emotes and silly in-game moments (like picking up chickens) are brilliant, along with the cheesy dialogue.
- The combat is surprisingly nuanced and you can definitely get a lot better with some practice. Good players stand out a mile. Kills are satisfying and sufficiently meaty.
- The maps and objective game modes are good fun, so just mess around with classes and have a blast.
- Dev support is really good and has been consistent since launch.
- Stick with a particular weapon for a while. It usually takes some time to get a feel for it, find the range and how best to use it.
