Tiberian sun cheats

There are no specific cheat codes for Command & Conquer: Tiberian Wars that I know of. I have looked personally for a long time and I still have seen none. There are Hints that are to some extent usefull, like the infinite firewall for GDI. One hint I find very useful, depending on the tech level, is the steel walls that can be built by both teams. You can build walls all over as long as you start from your base. A really nasty trick with this is build the walls all the way to your enemy's base and close up his/her refinery, barracks/hand of NOD, and war factory. This will give you some time to build up a force or build a bigger base
