There are no real cheats for any Westwood game but these may help. They are cool too!!!
The Secret Ant Missions
To access the hidden giant ant missions, hold down the left Shift key on your keyboard, and then right-click on the speaker above and to the right of the Options menu. Counterstrike CD required.
Tesla Tanks in Skirmish
Then you enter Red Alert, click on the New Missions bar. Then, click on the mission The Legacy Of Tesla. Build all the required buildings until you can build the Tesla Tank. Then abort the mission. Now click on Multi-player Games. Select Skirmish Mode. After you start a game, you should be able to build Tesla Tanks.
On the last Ant mission (very hard to get to!), save your game and then load up a "build - a - base" mission. Sell a couple of buildings and you will hear "New Construction Options". You will be able to build a queen ant.
Build 2 Tanks At Once
With this cheat, you can build two units at the same time. Build about 5 war factories. Build a tank and at the very last second, switch primary buildings. Then build the unit and switch primary buildings again and then build another tank.
To build unlimited aircreft, start building the airfield and the aircraft. Then, cancel the airfield and continue building aircraft.
To find out if mines are near your base, build a structure. When it is finished don't deploy it. Slowly sweep the WHITE outline of the structure around your base. If one of the squares in the outline turns red, you have found a mine. (Don't wander to far away from your base or the whole outline will tern red)
You can find enemy subs by selecting a naval unit such as a transport and moving the cursor over the water areas on the map (not the main screen). If you get the red icon for attack, then there is a submarine there.
Speeding Up The Slower Units
Cruisers and other naval units can move at the same speed as a transport if grouped together and then placed in formation (press 'F' while grouped). The Minelayer and ground vehicles also can be grouped together with a faster unit and placed in formation, although this is not as noticeable because the minelayer isn't particularly fast.
No need To Store Ore
Whenever you start building a structure or unit the money for it comes from any stored ore before draining your cash resources. However, if you cancel the building you will be refunded the cost so far in cash no matter what was used to pay for it. So there is no real need for silos.
Long Range Grenadiers & Rocket soldiers
Grenadiers and Rocket soldiers can throw(fire) all the way across the map. First build a bunch of grenadiers or rocket soldiers. Force fire on the terrain just in front of your grenadiers. When their little arms are up in the air, just about to throw the grenade, fire somewhere else farther than their range. These grenadiers can be as deadly as cruisers once you perfected the moves. This takes practice.
The end Credits
When you click on the Westwood Icon in the upper left side of the screen it plays the credits.
Red Alert 2
Want to have some fun with the enemy player? Charge up the Chronosphere and use it on the enemy unit, then drop it in the water. Watch the war miner go down to the bottom! Bye bye. Also try it on ships and drop them on land. Killing an entire infantry group is fun since infantry can die under the effects of the Chronosphere. Go ahead, try it!
The previous cheat refers to the Iron Curtain as well, fry those GI's!
Chrono Legionnaire (1):
Put one Chrono Legionnaire inside an Infantry Fighting Vehicle (IFV) to make a Chrono Fighting Vehicle. The Chrono Beam doesn't get any stronger, but your units won't die as easily.
Chrono Legionnaire (2):
Chrono Legionnaires packed together can even zap an enemy building out of time, try it. Ten Legionnaires and above give the maximum effect.
Build five or six demolition trucks. Make sure you have a fully charged Iron Curtain. Send the Trucks into an enemy base, before they come in range of their weapons, cast the Iron Curtain on them. They'll be invincible until they reach their target, at which point they'll still explode even with the Curtain on.
The Magic School Bus (Soviet):
Take a Yuri and mind control a school bus (if they're on the map). You can put five infantry into the Bus and drive it into an enemy base, they won't fire on it.
Good Use of the V3:
If you play as the soviets, one of the best way to use the V3 Rocket is to have about 3 Rhino tanks for each V3 Rocket to protect them. If you have about 5 V3 Rockets and 12 - 15 Rhino tanks you can take out a medium base! One of the reasons is that the V3 Rocket fire very long!
In Multiplayer or skirmish mode, use spies to infiltrate all enemy battle labs. This is to train new units like the physic commando (he can use the mind control and plant C-4 on buildings). Later, if you capture the base completely (meaning all buildings) you will get the Yuri Prime.
Excellent Base Defense:
Make 10-12 Yuris and place them all around your base. Put them as team1 (Ctrl + 1) then when an enemy attacks use the Yuri's 2nd attack. This should destroy most of the attacking force.
Last Allied Mission:
There are many buildings. Use them to protect your base plus your Chrono Miner and repair it if it is damaged. You can get free GIs if you capture the Tech Airport up North. Garrisoned buildings work well against the Soviets as they have no form of air attack and usually forget to us their V3s.
Build Defense Anywhere:
This cheat only works if you are America. First get your paratroopers ready. Then build a Prism Tower or Pillbox. I prefer the prism tower. Next click on the paratrooper tab. Then Wait a little while and click on the defense you chose. Finally click anywhere on the radar screen. The defense should be somewhere around where you clicked. NOTE: This does not always work.
Build Anywhere With Allies:
First you build a Chronosphere or Weather Storm, if you are allies. Then build an object (barracks, dock...) When it is full you click on the icon of Weather S. or at Chronosphere. Warning! Weather storm or Chronosphere must be full! And click on the icon that looks like a house, then click on the building that you built. And click on the radar view anywhere. And that's all!!
Build Anywhere With Soviets:
See above for allies, but you must build Nuke silo or Iron Curtain.
The Ultimate Tanya (Allied Only):
Build a Chronosphere then a Tanya and IFV. Put Tanya in it and use the Chronosphere to drop the IFV in the enemies base and deploy her. Get her to demolish as many building as she can.
Transport Your Entire Army:
The Soviets the armored transport can take 10 infantry or 2 vehicles If you load an armored transport with another 2 ATs that in turn are loaded with 2 more ATs that are loaded with another 2 ATs that are etc.,etc,etc ........ then you can put your tanks and infantry in the final set that you make. Now you can transport your whole army across water!!! This is particularly effective if there is some empty land near a river and near the enemy if you want to setup and you want to setup base there.
Tricks for Spies:
Place a spy in an any enemy barracks for veteran (one stripe) men, or in any enemy war factory for veteran tanks etc. Place one in an enemy Allied battle lab for a chrono commando (has a rapid fire machine gun and explosives like Tanya). Place one in any Soviet battle lab for a Psi commando (controls units like a yuri, has explosives like Tanya) Having infiltrated battle labs, if you capture (or already have) a Soviet barracks, you can now buy one Yuri prime (two with cloning vats) with a long range for controlling people, and a chrono Ivan (just like Crazy Ivan, but chronoshifts). Place a spy in an enemy power plant to knock out their power for a while. Place one in an enemy radar of airforce command centre to bring down their radar.
Easy Spy Disguise:
A spy can get a disguise from an enemy soldier, dog or even a cow..
Ultimate Sub Defense (allies only):
If you really want to protect your naval base, just surround it with dolphins and prism towers. The dolphins attack will make the subs surface ant the prism towers will shoot them.
Get The Chrono Commander:
In a skirmish game. Play allies against allies. Build a spy and have it infiltrate their battle lab and you will get the chrono commander.
Tesla Coil Trick:
3 Tesla Troopers build as quick as 1 tesla coil sobuild them at the same time, when youve got a coil down tell your 3 troopers to charge it up and build a wall around the tesla coil and troopers, it will protect them from groups of dogs and snipers.
The enemy usually goes for your war factory and it always destroys it, if you build 2 war factorys far apart from each other and well away from barraks, superweapons etc. If you build a naval base the computer sometime goes for that and never destroys it=).
Excellent Defence from Harriers:
The computer usually sends the harriers to attack your ore refinery and when u kill them with your patriot missles (allies) or flank canno n(soviets) they still come down and destroy you. Find out witch direction the harriers are coming from then build an MVC or move your main one to where the harriers are coming from. Leave a big space to let them crash then deploy your MVC build at least 5 patriot missles (allies) or flank cannon (soviets) in a row then move your MVC out of the crash area. Voila! no more worrying about harriers!
When you play as allies, you can make your jets invincible at anytime... When they're about to take off, push guard and they will try to land again but then tell them to attack. Then, when the enemy shoots at them they will be invincible. Works better on black eagles.
Clone Units For Practically Nothing:
Take over a hospital, and build a Cloning Vat (if you dont have one take over the NME base). Get an expensive unit or one that takes a long time to make. Get a machine gunner and shoot the unit. Then tell the unit to go repair itsself in the hospital... tadaa! Look at the cloning vat: another unit! This only works for people and I'm not sure if it will work with Yuri/Yuri Prime.
If you take a Crazy Ivan inside a I.F.V. You will get a demolition truck.
Terror Drone Defense (Allies):
If terror drones are continually attacking your tanks, create a couple of repair IFVs (IFV and engineer) and put them into gaurd mode (press G). The IFVs will rush around repairing vehicles and destroying any terror drones that get inside vehicles.
Nuclear Base Defense:
This is soviet only. Build nuclear reactors around your base (quite far from your base) then build a Crazy Ivan (one for each nuclear) then tell your Crazy Ivans to blow up there nuclear reactor when the enemy comes. (if you cant/dont want to build Crazy Ivans destroy the nuclear reactor till it has 1 square of life left then get a conscript or tank, etc. to destroy it).
Prism Tower Defense:
As you will learn during one of the single-player missions, Prism Towers can be placed in close proximity to one another to increase their power. This is similar to the way the Soviets place Tesla troopers adjacent to Tesla coils to increase the defensive structure's power. Careful placement of Prism Towers can increase their potency by tremendously. Use the map's landscape to your advantage when forming your base. Leave only a few available entrances and defend these with a few Prism Towers in close proximity to one another to increase their power.
The Soviets can reign supreme on naval maps as long as your fleets are mixed and well protected. But using dreadnoughts alone is not a good thing. You will need a good mix of ships to protect your naval fleet. Sea scorpions provide anti-air defense against harriers, racketeers, destroyers, and aircraft carrier hornets. Also, subs can be used to down destroyers and fight dolphins. Finally, use squids to take down carriers and destroyers.
Watch out for the Bombs!:
If you want to anger your opponent, Libya is the way to go. Build an Iron Curtain device when time permits. Two minutes before the Iron Curtain is ready, build three Demolition trucks. Once the timer reaches zero for the Iron Curtain, move your trucks into position near your enemy's base. Select the Iron Curtain device on your trucks and send them in. Since your trucks have invincibility for a limited time, decide what buildings would best to destroy. You'll have your opponent asking for a rematch in no time.
The Kirov airship is one of RA2's most devastating units, especially if ignored by your opponent. It takes heavy anti-air defenses to take one down. Although the Kirov moves slowly, if you can get one attack run on an unprepared enemy, you're likely to win the game. A Kirov can survive air defense for a small amount of time, but it's wise to group one or two Kirovs or send in a diversionary ground force such as Rhino tanks and Flak Traks. Using these units in combination with each other will ensure victory.
The Easy Time Bomb (soviets):
If you are in a level with a lot of cars and you are going for a long game then get a Yuri and a Crazy Ivan. Set the Yuri on one of the cars so you can control it. Then put it close to the enemy's base. Now set a bomb on it and drive it into the base -they will not attack it. This can be really effective if you do it numerous times.
If you press Triangle, then select your guy to train, press Trianle again, and hold R1 and press O. Now you can train recruits while infiltrating the Soviets! Same applys to buildings, but the second time you press, you lay the building down. Have fun, and kill nicely!
Easy Spy Infiltration (Allies only):
First build a War Factory, a Barracks, and a Tech Center. Biuld several IFVs and the same amount of spies. Put the spys into the IFVs. The IFVs will act the same as if you put GIs in them. Send the IFVs to the enemy base and get one close to the building you want to take over. Unload the spy and he will run into the building without taking damage.
