I've found out that it is a flaw in the programming. In co-op mode only player 1's stats
get saved and player 2 gets reset whenever you stop playing. I checked out the resistance
beta site and I guess they may make a patch, but I doubt it.

talking about its a bug and its just too bad for you cause theres no way to get them back
if you were a high level like i am man that must **** good luck getting ur stats back

It is probably corrupted data, as this happened to me...twice. Make sure you back up your
data onto a SD card. And to stop it going corrupt, make sure you save evrything, and quit
the right way, rather than just swoitching the system off directly.

theres no way resistance 2 has any flaws
possible that the first one does
but my point is it was probably not the games fault

but check your system that might be it

It happened to me. I think its coz my little bro always switches it of halfway through my
game so I can play outside with him. Hes only 5.
