A handy little kit for those that can't upgrade their Call of Duty 2 to version 1.3 due to errors. (mostly caused by previous installs of the patch). Also the kit contains a full description on how to install both 1.0 and 1.3 on your pc.
This is a kit containing the files and instructions needed to downgrade version 1.2 to version 1.0. It's very handy since all new copies sold now of Call of Duty 2 are version 1.2.
