EA announces that Command & Conquer Red Alert 2 and the Yuri’s Revenge expansion for the RTS sequel are now free on Origin as the latest installment in their On the House program (thanks Ant). There are no strings attached besides the use of Origin, as those who act on this offer will have both items permanently added to their libraries. Here's a refresher on the game, which first launched in 2002:

The world erupts in conflict as Soviet forces invade American soil in Command & Conquer: Red Alert 2. Time travel has helped to eliminate the German threat, and now the Soviets are expanding into the West unchecked. You are the Supreme Commander. Arm yourself to the teeth with top-secret technologies and lead the Soviet or Allied troops to victory.

Plus, defeat an army of mind-controlled Soviet forces in the expansion Command & Conquer: Yuri's Revenge.
