Though, as I've read on the german forums, Windows 2000 isn't fully supported. To prevent crashes running with Windows 2000, I advise you to get the latest service packs for 2000 and drivers for your additional hardware. The game requires 300MB of harddisk space, a lot for a strategy game. After starting the game, viewing 3 movies including the intro, I ended up in the main menu where you'll see the different submenu's. Multiplayer, Single player and Options.
Single player has single missions and campaigns.
In the game's campaign menu you can choose to launch a new campaign, or load an existing campaign. I choose for the Russian Campaign. You can ofcourse choose for the Germans or Allies as well. Some of the campaigns include very neat missions, imagine D-day or Stalingrad, and boy I can tell you that those are very hard to play and you'll need your pause button. Terrain One of the most interesting things of this game is its unique feeling of a real battlefield.
