Build anywhere: Build sandbags from one of your buildings to where you want to build, and build next to the sandbags. Then, sell the sandbags.

Extra cash bug: When you sell three refineries right after each other, the money you get keeps going up until the end of the mission.

Surprise attack: To catch your opponent off guard, build (and charge) an Iron Curtain. Then place it in the midst the enemy, on a structure or tank.

Bonus missions: In MS-DOS mode, go to the directory you installed Command & Conquer in and type “c&c funpark”. When the game begins, select START NEW GAME and choose either side for five new missions.

Extra cash: Let a silo fill up half way then sell it.

How to sell vehicles: To sell a vehicle, place it in a repair bay, then choose the $ cursor and place it over your vehicle. You’ll get about the half the value back.

Space ship: To find a space ship, go to the GDI level 6: Czech Republic. Build a normal base. Blow up all SAM sites. When you get the airstrike option, use it to attack the bottom-left corner. If you don’ see a silver ship, attack with airstrike a little higher than you did before. You should see a silver space ship that crashed.

Steal Enemy Harvesters: You can steal the enemy’s harvester by capturing the refinery while the harvester is depositing money into it. This comes in handy on earlier missions when you cannot build more harvesters.

Build Anywhere: Build a sandbag wall next to one of your buildings. Now continue the wall until you reach the spot where you want to build. Build your new building, and then sell all the sandbags.
