Treyarch details - little-known facts about Call of Duty: Black Ops

In a guest blog spot on the official PlayStation blog, Treyarch community manager Josh Olin has discussed in detail a few of the lesser-known details about its upcoming shooter Call of Duty: Black Ops.

First of all, Olin discusses what he believes to be "the most unknown, yet confirmed, aspect to Call of Duty: Black Ops multiplayer - the online split-screen support we've re-introduced to the franchise!"

Olin writes that (much like in the Halo series) you can connect a second controller and bring a guest online. Best of all, your guests can still rank up and earn unlocks, although they will lose this progress once they sign out.

Black Ops will also feature a Custom Games Editor, which gives players "the ability to structure their games at all new levels of granularity". Players can modify aspects such as the time limit, score limit, available weapons and much more. Custom game types can also be uploaded to a file share so they can be accessed by the wider community.

The game will introduce an in-game friends list user interface, which simplifies the process of joining games with your friends and recent opponents, not to mention browsing their file shares and combat records.

Black Ops will support regional matchmaking, much to the delight of Australasian players, and Olin also confirmed that custom emblems will not reset once a player achieves Prestige class.
