actually the DRM is working. If you take the time and go visit pirate boards you will see people jumping for joy over sh5's crack only to see them complain about not being able to even complete the first part of the career. It must update the servers or vice versa once you complete an objective, then UBI's servers sends the proper data to unlock other missions or whatever. At least thats the theory..
I can say though im done with the SH series. Im sick to death of the current problems of sh5, floating rocks, pathetic depth keeping, apparently im stupid cause even using the auto TDC i cant hit the broad side of a barn. Real tutorials would have been great!..too bad they forgot about it. Oh then dont forget about running into a massive convoy, just asking for torpedos only to see a net disconnect and a autosave failure.
Id go to sh4 again but im sick of the campain save corruption issues...wth couldnt they have FIXED that before creating a new one?...nope.
For now its on the shelf and uninstalled, maybe in 2 years someone will fix the problems. All I know is UBI will NEVER get my income again.
sorry for the negative attitude but i hate spending 50 bucks only to find its a dust collector.
