So… ever since the challenge started (see here: Question about events - #7 by Thunderblt123), there’s been a bunch of bugs going on, not only with the leaderboard but also with a lot of other things in-game. And, now, today’s the day, the challenge is over. From the looks of it, nobody has really went up on the leaderboard. So, instead, the skin has just been added as a secret skin. If you want to unlock him, you have to figure out what the code is. I’ll give you one hint to start out with, the name of the skin is Raze, that has something to do with the code. Otherwise, that’s it. Play Arena Nexus here and try to figure out the code: Arena Nexus - Season 1 | Play on gd.games
Also, I fixed some bugs in the game.
