Command & Conquer: Red Alert (PC)

Beat Soviet Convoy Mission
The Soviet mission - the one in which you must destroy an Allied convoy -
can be accomplished in under a minute! At the start of the mission, pursue
the convoy that is heading north with all of your units. (An armored tank
division flanks the Allied convoy, so it is easy to overtake.) Next, unleash
the potent firepower of your combined forces. The Allies won’t know what hit
‘em!

Construct Bases Anywhere
To construct a base that isn’t connected to the current one, build a silo
beside an existing structure. Then contiguously erect silos until you have
reached your desired construction point. Afterwards, sell the silos and
build your base!

Faster Sailing
Having certain naval vessels within the formation will increase the overall
speed of the fleet. When a slower ship (such as a Cruiser) is coupled with a
speedier one - like a Transport or Minelayer - the entire fleet will travel
at the rate of the fastest ship!

Free Men
Build a missile silo. When the missile is ready, sell the silo and
immeidately launch the missile. If you were quick enough, the sale will have
stopped and some troops will come out of the silo.

Long Range Grenadiers
In multiplayer or the regular game, play as the soviets. Next, build a
grenadier and have him force fire on the ground around him. Right before he
throws it, click anywhere on the map and the greade will SAIL over to that
point.

Russian Tip
When playing as the Russians, build a Tech. Center. After you build it, sell
it. All the special characters you get from the Tech. Center will still be
available, and you get back all that wasted energy you used on the Tech.
Center. You can now build more Tesla Coils to protect your base, and still
have Tanya and the Mammoth tank!

Secret Mission: It Came From the Desert
To access the secret mission, “It Came From the Desert”, press the [Alt] and
left-click on the speaker in the upper right-hand corner.

Sell Your Vehicles
To sell your vehicles, build a service depot and place a vehicle on it. Next
put the SELL cursor on it and when it turns green press the left mouse
button. This doesn't work with V2 Rocket Launchers.

Selling Tanks and Harvesters
If you want to sell your vehicles, like the ones you don't want or you are
out of money and need that last little bit then this is the code for you.
Here is what you do: build a Repair Facility and drive a tank or vehicle
onto it and while it is on the very edge put the sell button on it and it
will sell. (The sell icon will be green if you catch it at the right time.)
My suggestion is to have the sell button ready.

Soviet Playing Tip
When playing as the Soviets, when you have a Iron Curtain and a Missle Silo,
send a tank into the enemy base. When he is attacked, use the Iron Curtain
on him. When lots of enemys come around him, launch the atom bomb.
