Redacted Change Prestige & Stats commands.
Just to mention, if you change any stat, it will effect the files and you will have to restart over.
I also own 2 copies of the game, i just copied the folder and installed redacted lan.
Code:
statsetbyname plevel 1-15 // Changes Prestige.
statsetbyname score 420 // Changes your total score.
statsetbyname kills 420 // Changes the amount of kills you have.
statsetbyname wins 420 // Changes the amount of wins.
I guess there could be a way of unlocking camos by changing other stats.
Again, this will give you the "server disconnect" message and you will have to restart.

I don't get the server disconnect thing. I just get server disconnect with and bunch of numbers. This also accured back in the day when you modified your xp with cheat engine. After closing and restarting, the same error is still present.
once started the game with xpartygo command, type on console line command:
bot_difficulty (0-3)
0-Recruit
1-Regular
2-Hardened
3-Veteran
