Despite many of the launch titles being available for both current generation and next generation consoles, it's looking like Infinity Ward and Activision are having to make some sacrifices to the current generation version of Call of Duty Ghosts to ensure things run smoothly.

Thanks to a new leaked image of the back cover for the Xbox 360 version of Call of Duty Ghosts, we now have found out that the online multiplayer will only feature up to 6 versus 6 combat, with the largest games only having a total of 12 players, instead of the standard 18 seen in previous COD games.

On the next gen version and the PC version of Call of Duty Ghosts, the 18 player standard is present, so it looks as if sacrifices have had to be made. Although we haven't seen a PlayStation 3 copy of the game, it's likely that PS3 will only support up to 12 players online as well.

The leaked image also gives us information on the mandatory download for COD Ghosts on the Xbox 360. Luckily, it will only take up 3GB of storage space, which means that even if you don't have a hard drive, you'll still be able to install the game onto your hard drive and play the full game once you've cleared a little space.

It will be interesting to see what other sacrifices have had to be made to make sure Call of Duty Ghosts run smoothly on the Xbox 360 and PlayStation 3. Details are quite sparse at the moment, but I'm sure we'll notice a difference once the game releases.
