I have had this game for about 2 months, and you're right. It ROCKS ! I am very addicted to it. I gave a couple copies of it for Christmas presents so my friends and I can play online. It works with GameSpy as well, which is a plus.
Unfortunately, I don't know of any cheats for it....
The thing I really like about it is when you select a group of units to attack as a Task Force, they attack together. The faster units will wait for slower units so that they arrive at the target simultaneously. I can't tell you how many times in Red Alert that my tanks went streaming one by one into an enemy base, getting shredded in the process.
If you like RTS games, this is the one !!!
