Hi Guys i just need so info here.. I have purchased some games for the eldest lad and while he was at school i wanted to test them but in doing so i have just realised that an achievement slots have been created and he is sure to see what games i have bought him by looking at the game names,the files without any achievements can be deleted by pressing `X` but it says he needs to be connected to X-box live (which he does not have at this time) is there any other way? If not i will have to tell him as i cannot delete his profile he has too many other achievements on
I'm pretty sure they are there to stay :-( but I would say for future use, when you want to test a game just set up a second account on the console, test the game then delete the account.
If he is really desperate to see that 'acheivement unlocked' for himself, he could also get those achievements on a second account - they wouldn't add to his score on his main account but he can say he'd got them.
edit:
when you delete the account make sure it's the 'fake' one for gods sake LOL
