-During a skirmish game, play on Yuri's team and build a Cloning Vat. Train a Yuri Prime. Go to the enemy's base with the Yuri Primes. Capture any part of the base, then sell them. Note: Get the base defense parts first and use them to kill enemy units around the base.
-Yuri is required for this trick. Build Cloning Vats and a Grinder. Build Infantry and send the clones into the Grinder. You will get free money because you never paid for the clones.
-While playing as Yuri, get control of the Genetic Mutator and build the Cloning Vats. Deploy it near or beside the Barracks, then train about 20 Initiates and the Cloning Vats will double it to 40. Take your 40 Initiates and bring them to an open location. When the Genetic Mutator timer runs down to zero (0:00), activate it on all 40 Initiates. They will all turn into Brutes. Instead of putting 40 Initiates in the Grinder, you can now put 40 Brutes in there, which gives you more money. Repeat this to receive additional funds.
-Play on Yuri's team during a skirmish and play on a level with an civilian airport on it. Capture the airport and build a Grinder. Every time you send down reinforcements, put them in to make a profit of about $500. Since you never run out of reinforcements, you can repeat this to never run out of money.
-Play as Yuri in a multiplayer or skirmish level with a city. Make sure that there are civilians or vehicles in the city. Create a Grinder and any amount of Mind-Control units. You can mind control the civilians and vehicles. Send them to the Grinder for a free amount of money. Matrix Pixels.
-As Yuri, train a Yuri Prime (you can use a Cloning Vat to train two) and take it to the enemy base. Capture any building and sell it right away. You will get the money and Yuri will be able to take over the next building.
-During a skirmish game, build everything you need to generate at least two UFO units. Find an enemy base and use one UFO to power down the base while the other covers the first. Once the ground is clear of any offensive or defensive threat (such as Flak Troopers, Guardian GIs, Patriot Missiles, etc.), send the remaining UFO unit to the enemy's Oil Refinery. The siphon on the UFO will transfer somemoney from the enemy refinery to your bank (at a rate of about $20 per second). If you keep continue to do this, you will eventually win; not to mention fund anything else you would end up building. This is an especially good tactic to use against several enemies.
-Note: Yuri is requiredto complete this trick. Make sure you have a Grinder. Capture an Airfield in any map with one, then paradrop your Paratroopers in your base and send them into the grinder. This prevents overcrowding and gives extra money.
-As Yuri, acquire a fully charged Genetic Mutator, Cloning Vats (optional but recommended), Meat Grinder, and tonsof money. Create a large army of Initiates and bunch them up in one location. Use the Genetic Mutator and turn them into Brutes. Then, send the New Brutes into your Meat Grinder.
