Westwood Studios' genre-shaping 1995 real-time strategy classic loads in seconds, putting you in command of either the global Brotherhood of Nod or the international GDI.

Build power plants and refineries first — your whole war machine depends on Tiberium income and a steady power supply.

What Is Command & Conquer?

Command & Conquer is a real-time strategy game developed by Westwood Studios and released in 1995 for MS-DOS. Set in an alternate present where a mysterious alien substance called Tiberium is spreading across Earth, it pits two factions against each other: the Global Defense Initiative (GDI), a United Nations-backed coalition, and the Brotherhood of Nod, a shadowy techno-religious organization led by the charismatic Kane.

Following hot on the heels of Westwood's own Dune II, Command & Conquer popularized the modern RTS template — base building, resource harvesting, and real-time unit command — and made it a mainstream hit. With its live-action mission briefings, memorable soundtrack, and two fully distinct campaigns, it became one of the most influential strategy games ever made and spawned a long-running series.

How the Game Works / Gameplay Basics

Every mission revolves around the same core loop: gather resources, build a base, produce an army, and destroy the enemy. Harvesters collect Tiberium and bring it back to your refinery, converting it into credits you spend on structures and units. Power plants keep your base running — let your power drop and your defenses and production slow to a crawl.

From your construction sidebar you build everything from infantry and harvesters up to tanks, artillery, aircraft, and defensive turrets. GDI fields powerful conventional hardware like the Mammoth Tank, while Nod relies on speed, stealth, and weapons like flame tanks and the devastating Obelisk of Light. Success comes from balancing economy, defense, and a well-timed attack — turtle too long and the enemy out-produces you; rush too early and you'll run out of steam.

Beginner Tips

• Build economy first. A refinery and a second harvester early on fund everything else.
• Protect your power. Damaged or destroyed power plants cripple your base, so defend and repair them.
• Use group hotkeys. Assigning units to Ctrl+number lets you command armies quickly mid-battle.
• Scout before you commit. Knowing where the enemy is heavy or weak saves you from costly mistakes.
• Match units to the threat. Send infantry against infantry, tanks against armor, and keep a mix so you're never countered.
• Play to your faction. Win slow and strong with GDI, or fast and sneaky with Nod — don't fight against your side's strengths.

Why Play Command & Conquer Online?

Playing Command & Conquer in your browser is the fastest way back into the game that defined real-time strategy. There's nothing to install and nothing to configure — a title that once shipped on CD-ROM now loads with a single click. It's ideal for a quick nostalgia hit, for replaying both campaigns, or for showing a newcomer where the modern RTS genre took shape.

Because it runs in the browser, you can jump into a mission on almost any computer without touching your hard drive. For a strategy landmark this important, that kind of instant access is hard to beat.

Troubleshooting

• Game won't start? Refresh the page and give it a few seconds to load fully before clicking.
