The system is available only to registered players. Levels table:
You can see your progress in settings page. The appearance of a knife in the game can take up to 15 seconds after entering the server. The system works on all servers, except thematic (S.T.A.L.K.E.R., Star Wars, etc.). You can get level on any ranked server!
What about when you earn a knife you can switch back to that knife anytime in the menu? That way if a player wants to keep / stay with a knife they dont have to be scared about getting more knife kills . To do this you would just have to add a section of the shop thats tilted KNIVES and put all the equipable knifes there. Just like the skins used in the shop. Another feature that would be harder to implemant but would be cool to add would be to show how much more knife kills you need in order to get the next level of knife. I would really want this implemanted into the game, that way when I get butterfly knife I dont have to be scared of getting more knife kills in order to advance to the next level, and I think the community would like this too. Thats it, and thank you for reading.
