The Splinter Cell Website has word on plans for limited edition versions of Splinter Cell: Chaos Theory, the upcoming continuation of the stealthy action series. There will be special versions of the game "produced in very limited quantities" for all platforms, which will sport a metal box and a disk of additional content. The announcement also has word on a bonus for PC owners:

Packaged in a unique metallic embossed collector’s box, the two-DVD set will contain the full-version of the game on Disc One plus the making of Splinter Cell: Chaos Theory and Development Diaries on the A.I., level design, animation, graphic technology and more on Disc Two. It will also feature an art gallery, the Penny Arcade spy training manual, video features and trailers. PC owners will get a special treat as the PC version will exclusively feature three playable levels from the original Tom Clancy’s Splinter Cell: Kola Cell, Vselka and Vselka Infiltration.
