Command & Conquer: Red Alert 2 Tips

Unlimited money in skirmish
Go to menu for skirmish and select a team (doesnt matter wich). Then you press the button "customzise battle" and then you will get a menu with lots of maps. Then you go downwards, almost to the bottom, and you choose the map "training map" or something like that. When the game has begun you build two engineers. Send them to the middle of the map. There it is two houses who looks like an airport. Send the engineers into the buildings. Then you will get unlimited money, and lots of other cool stuff.

Hope this will help you.
