Hey Chausta,
Thank you so much for the feedback I really appreciate it. I had recreated the player manager and input system to fix the multiplayer issues and really have mostly been testing the game on the PS4 or with a PS4 controller but you were completely right about the Xbox controllers. I just uploaded the fixed version for the Xbox controllers, at least I think I did as I don't have any xbox controllers around to test. Please try again and let me know if its working and if it is showing the right interface buttons for the xbox I would really appreciate it.
For the cheats, you just have to be joined in and press each button of the sequence quickly.
Thanks again Chausta you really saved the day,
Rafi
