To confirm, I'm on the weapon select screen, I press F7 or F6, select the weapon and hit customise. The price is still the same
But out of curiosity im wondering why they would go to such length to stop cheating. After all its my game i payed for it and should be abel to cheat if i want to. Or no ? Why would they even care?
for cheat 7 i got all of them to work.
just keep spamming the button and checking the upgrades till they work.
hope that helps a bit.
so for cheat 6 i couldn't get it to work except for slot 3. which is fine since all the upgrades before that cost about $30k total.
Yeah I have to say option 6 only opens slot 3.
Also option 7 I had to spam the key a lot to get it to work.
