If you own Unity of Command buy this expansion. As already mentioned in my Black Turn review there is no compromise in quality and if you can pick up Unity of Command with all the DLC's in the sales it really is a no brainer...
Dying days of the Stalingrad Campaign saw the Wehrmacht reeling under heavy blows. The battle of Kursk will now see them pursue an offensive agenda for one last time. Soon after, as the strategic initiative swings in favor of the Soviets, you are tasked with liberating the motherland in command of victorious Red Army forces.
