1 - Get some cases.

2 - Go near current mission endpoint.

3 - Deposit your cases and run fast to the checkpoint.

4 - Your likes will increase infinitely.


5 - (optional) buy 1000 cans and run everywhere


I'd recommend to deposit at least one other case to stop it, or in some cases you'll lose everything when you buy something.


This theoricaly works for every act and every mission, but the further the point, the more cases.
