Command & Conquer: Red Alert 2 Tips

No More Enemy Base
play a game in skirmish mode and play as France. have an soviet enemy and start building until you can build a battle lab. Build a spy, disguise him, and infiltrate the soviet battle lab. You should get a psi commando. Then, build an engineer, a grand cannon, 2 IFVs, and a psi commando. DON'T PUT YOUR GRAND CANNON OF THE FIELD YET!!! Put the engineer and the psi commando in the IFVs. drive it near the enemy base but not in range of any defences. take out your psi commando and the engineer. use your engineer (without killing it) to capture any building and immediately build your place your grand cannon next to it. Have your psi commando stand next to it (without getting it killed). Don't worry. a Tesla coil that's being repaired by that twisting wrench thing is no match for a grand cannon. The purpose for the psi commando is that the grand cannon can't attack anything that is right next to it. the psi commando can defend it. Do this as many times as you want and soon, you'll get your opponent's base and destroy buildings at the same time.
