I played CRYSIS 2 online since day one. It's over six months and I still don't have it BUT my brother dose. I let my brother play CRYSIS 2 since day one and he got the DEDICATION TROPHY on the sixth month! How could this be? Well...my bro never rebooted his nano suit. I rebooted my suit on the fifth month because I was unable to unlock the last weapon ( C4 ) when I reached level 50! Two of my other friends have the same problem I'm having. So my theory is when you reboot your nano suit BEFORE the sixth month "since day one" IT RESETS! I don't know if you are able to get the trophy after playing another six months again. Please remember this is only a theory, I could be wrong. Thank you for reading.

i didn't reboot my nano, i had all other trophy without any problem, but this dedication trophy doesn't work !
