Thanks alot for the help.
I'm working for a game modification team called Ham and Jam, we are developing a free modifcation of the halflife 2 engine based upon battles the commonwealth forces undertook during World War two. I'm going to develop a level based roughly around Maleme with some of the major areas being included, ie the Iron Bridge, Airfield etc.
I'm also looking at possibly doing something based around Galatas area seeing there was some good action fought there over pink, wheat hill etc.
