"when playing online, its a good idea not to build nuclear reactors even if you have a thousand base defenses around it. If you must build it, make sure ur ally puts a gap generator in your base and make sure when it's built, it is hidden COMPLETELY. If they get a glimps of it, you can say bye bye." - runelemen

"TO get lots of money there is a simple trick. Make at least 50 spies and make them enter into any of enemy's Refinery (or Ore Miner of Yuri). It will be good if you let them spy the funds all at once. i.e all spies must enter the building one after another (select all of them and click on enemy's refinery or miner). the money will start increasing continuously and will never stop to increase. I made more than 10 million dollars in about two hours.

To increase building speed of units there is a simple trick. Suppose you want to make tanks fastly. For this you will have to make lots of War Factories ( Making more than seven will astonishingly improve building speed). Similarly to increase build speed of Army Men you have to build at least seven barracks ( the more you build the faster the production). to increase speed of production of buildings delpoy more and more of MCVs. To fasten up building of aircrafts build more Air Force Command Centers." - Shakir Zareen

"When playing as Soviet Union, take advantage of their mighty tanks and rocket launching capability. Build Apocalypse tanks and V3 launchers. Then attack! Apocalypse tanks lead the way and V3's follow close behind. This way the weak V3's are protected. Using this startegy you can blast your way into the enemy bases. You can also build some Siege Chopper's to further protect your V3's. Trust me, I have crushed countless enemies with this strategy." - Starbuzz
