Back2UO is a Call of Duty 2 modification which takes core elements of the original game play from CoD United Offensive and adds it to CoD 2. For example – the heads up display, functions, atmosphere and many effects.
This is a great mod! It doesn't have alot of features you will find in Extreme or AWE 3.2 but if you like the UO feel I think he did a good job capturing it. I haven't tried it with custom maps per the recommendation in the readme but that would be a huge bonus especially with all the UO custom maps out for COD2 like Cassino and Tigertown......Arnhem, someone needs to make an Arnhem map for CoD2.
