There are only 6 achievements in the entire game, which I think is a shame, but that doesn't bother us now.
I will now explain how you can unlock the individual achievements.

1.Create A Server
-> It's actually quite simple. You open the menu, select "Create game", select a certain map, and then you could adjust little things. And at the end just press "Start".
2.Joined A Server
->It's actually quite simple too. You open the menu, select "Browse Server "choose a lobby and join it.
3.Play All Mode
->In the entire game there are 3 different games where you can choose.
-> Free For All
->Team Deathmatch
->Free For All(Perma Death)
If you've played these three modes, you've made it
4.Discord
->This is actually given for free. There's a button in the menu that says Discord on it. Just click on it, accept the invitation and you're done
5.Credits
->Open the menu, select "Credits", and you´re done.
6.First Kill
->If you go into multiplayer you have to do the first kill at the beginning of the round. This is the hardest of all but should be feasible.


I hope I could help. Please contact me if you have any questions.
