The level-access cheats are all over the net. But they are not for the PC but for other platforms (nintendo/playstation or what).
If you want that use a searcher. Any of those will work (codewords: baldies, cheat or walkthrough).

My walkthrough is not an ultimate guide sience it is not possible as this is a real-time strategy. I only can suggest tactics, and basic strategy to start those levels. Basicaly if you can succesfully start a level you will win as the only thing that counts is the number of units in the end. I just report U how can U easely outnumber the C. on the beggining: with big red houses, with science lab, or U will specifically need soldiers, or everything fails so try a car. That is the most I can do. But ask questions and I try to help U specifically.

On level 3 U say? Which world? The first? That sucks. The C. wont build too much or fast, so don't mind it, just build as soon as possible the biggest red house, than build another, than kill the C.'s men. It is that easy. Oh, and if you have just small time to play use SAVE. If U do not want to play again all levels use those arcive saves. All in all: if U want I can send U MY best save in e-mail if U want it. That's the most I van do.
But I ave to learn a lot these times so I'm still didn't played any new levels. Just tried out the next to see where are skunks, how many place and enemy will there andso. There will be 3 separated island far away from each other, and 2 enemy. The blue is the strongest as always. Bilds fast, at least RL2. I could capture the other for good, but I would be too weak after that.
