What Is Command & Conquer: Red Alert?

Command & Conquer: Red Alert is a real-time strategy game developed by Westwood Studios and released in 1996 for MS-DOS and Windows. A prequel of sorts to the original Command & Conquer, it imagines an alternate timeline where Albert Einstein travels back in time to erase Adolf Hitler — only for Joseph Stalin's Soviet Union to rise unchecked and plunge Europe into a new world war. You command either the Allies, who rely on technology and finesse, or the Soviets, who favor brute force and heavy armor.

Red Alert became one of the most beloved RTS games of the 1990s, praised for its tight gameplay, campy live-action cutscenes, memorable soundtrack ("Hell March"), and excellent multiplayer. It expanded the Command & Conquer universe into a second long-running series and remains a defining classic of the genre.

How the Game Works / Gameplay Basics

Every mission follows the same satisfying loop: gather resources, build a base, produce an army, and destroy the enemy. Ore miners collect ore and gems and bring them back to your refinery, converting them into credits you spend on structures and units. Power plants keep your base running — let power drop and your defenses and production slow down.

From your construction sidebar you build everything from infantry and miners up to tanks, artillery, aircraft, naval units, and powerful defensive structures. The Allies field tech like the Chronosphere and longbow helicopters, while the Soviets bring heavy Mammoth Tanks, Tesla coils, and the devastating nuclear option. Victory comes from balancing economy, defense, and a well-timed assault — turtle too long and the enemy out-produces you; rush too early and you'll run out of steam. Both sides have their own full campaign.

Beginner Tips

• Build economy first. A refinery and a second ore miner early on fund everything else.
• Protect your power. Damaged power plants weaken Tesla coils and slow production, so defend them.
• Use group hotkeys. Assigning units to Ctrl+number lets you command armies quickly mid-battle.
• Scout before you commit. Knowing the enemy's strength saves you from costly attacks.
• Match units to the threat. Mix infantry, armor, and air so you're never hard-countered.
• Play to your faction. Win with Allied tech and mobility or Soviet firepower — don't fight your side's strengths.
