We have learned the location of the Chronosphere weapon, and we want to capture it.
The Allies have boobytrapped the Chronosphere to explode if approached. Capturing the tech centers BEFORE taking the Chronosphere may allow you to defuse any traps. Use extreme caution.
After the Soviet Commander destroyed the Allied naval forces, Stalin orders the Commander on his next target: the Allied Chronosphere. The Soviets have located the experimental superweapon near Seti in Switzerland, and Stalin wishes to claim the Chronosphere as his own. However, Kukov advised the commander to capture the three control centers to prevent the destruction of the Allied superweapon.
