Then build the unit and switch primary buildings again and then build another tank. Build a tank and at the very last second, switch primary buildings. With this cheat, you can build two units at the same time. Sell a couple of buildings and you will hear 'New Construction Options'. On the last Ant mission (very hard to get to!), save your game and then load up a 'build - a - base' mission. After you start a game, you should be able to build Tesla Tanks. Build all the required buildings until you can build the Tesla Tank. Then, click on the mission The Legacy Of Tesla. Then you enter Red Alert, click on the New Missions bar. 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. If you know of any bugs/cheats in Red Alert then please email me with a description of it. If you cheat in a multiplayer game against another human then you will probably become one of the most hated. If you do it against the computer in a Skirmish or mission game then the only person you are cheating is yourself. HOWEVER, I would like to point out that I DO NOT condone cheating of any kind. Some bugs can be used to cheat in the game and some of these are outlined here. Perhaps surprisingly, Red Alert has loads of minor bugs, despite being one of the most popular computer games of all time.
