I am an old user who used to hack and left CrossFire 1y ago. I got a tut for you on how to get free PSC and get free ZPs. Today redeemed 10k zp for 30 min work. So it's kind of good.
Now you got some points, let start to get massive points with kinda glitching:
6. Get a good VPN (link) and do step 1 to 5 again
7. On account one, go to https://paysafesparen.nl/kluissleutel and buy a 'Key' for 10 points
8. On account two, do the same, buy another 'Key'
Now somebody else also buys a key and there is a 76% change you win.
Now you got 25 points for free. Now keep repeating that over and over again.
