Had some spare time so made a script that will unlock all the usable cosmetics. This includes the old exclusives and the newer shop skins.
What you will need:
It's very simple, all you need to do is attach cheat engine to the game, go to Table > Show Cheat Table Lua Script and paste the following into the window that appears:
Now just execute the script and if all goes well you should now have every cosmetic unlocked. You only need to run the script once after every game launch. Feel free to use this script to help you write your own cheat, but if you use any of the information in this post I only ask that you give me credit. If anyone tries to leech this and pass it off as their own then I will not be releasing anything else. Oh and I am of course not responsible for any bans, use this at your own risk.
sig = "32 C0 40 84 ED 48 8B AC 24"
flags = "+X-W-C"
result = AOBScan(sig, flags)
if result.Count ~= 1 then
messageDialog("Invalid signature", mtError, mbOK)
local op = getAddress(result) + 0x0D
if readBytes(op) ~= 0x75 then
messageDialog("Unexpected instruction", mtError, mbOK)
writeBytes(op, 0xEB, 0x32)
messageDialog("Game has been patched!\n--xoreaxeax", mtInformation, mbOK)
