Hey mark I just found this game on Fileplanet called D-Day there is a demo out for it and it looks really cool.
I was gonna download from Fileplanet and if you want to just search there, but I decided to go with 3Dgamers because I didnt want to wait in line. Here's the link to the list of mirrors for D-day on 3dgamers http://www.3dgamers.com/dl/games/dday/dday_english_demo.exe.html
The demo has one single player map called "The longest Day" or something like that. It also has a Multiplayer map for up to 4 players, I'm downloading the game right now and so is dan, so eventually we should all be able to play online together.
Here some screenshots off IGN http://media.pc.ign.com/media/679/679190/imgs_1.html?ui=gamefinder
Hey mark there is 2 versions of Ground Control on Fileplanet. I'm not sure what one to get, but I'll wait until you take a look at it.
