Short point: An unfinished game released with an extremely high number of bugs that takes to long to get patched
This game was released by ubisoft for the PC as as a port from the X360 version, and for anyone new to the PC, THATS BAD. The game had so many glitches and bugs that it was unplayable for most players and for the lucky ones who could get it to work, it would usually get stuck on Shanghai and none of the unlockable gadgets would work (until near;y a month after the release)
This game also runs secuROM, which will conflict with virtual drives and burning software possibly making you unable to burn anything until; the game is deleted from your system and HIDDEN files the SECUROM LEAVES BEHIND AFTER UNINSTALLATION (that are protected and they won't even tell you how to remove them) are deleted too.
Sum it up: don't buy this crap
