The game have literally just came out, The developers of the game are working on the fixes. right now their money system and xp system is broken and you cant gain anything however they are working on fixing it. Overall really fun game
Currently you can't progress in the game. At the end of the games you get no XP or gold rewards which is required to unlock new items. Even if you do get xp and gold it tends to reset next time you launch the game. Apparently it's something their working to fix.
I'd definitely recommend it if they fix the current progression and matchmaking issues which they have addressed they are working on. If you enjoyed chivalry medieval warfare it's definitely a better version of that game
