Command & Conquer: Red Alert 2 Tips

Engineer Strategy
First, you'll need barracks and maybe cloning vats for the soviet. Build as many enginers as you can, at least 60 engineers for winning the game. Then, build lots of army and ask them to destroy all enemies' security buildings eg. prism tower, chronosphere, fillbox, gap generator and all thier units. Then, call all your engineers to "attack"(move to the enemy's base) and take over all their buildings one by one, this way the enemy will lose easily. This will be successful if you did it properly. Enjoy playing!
