About

3D Real-Time Strategy Redefined. The Total Annihilation Inspired RTS you've been waiting for. Explore the Scale and Realism: All units and projectiles are simulated in real-time. The game offers fully simulated projectile ballistics, explosion physics and terrain deformation. Enjoy an immersive RTS experience, whether you are commanding individual units, or armies of thousands. Take control as you engage in an epic struggle for domination! Strategic Importance of Terrain: The shape of every battlefield in-game imposes which strategies work and which units are effective to use. No two maps will play the same. Every terrain has a unit to match. Nuclear warfare can redefine the rules of the game. Utilize over 10 different unit classes, including giant Experimental units, to work your way to victory. Infinite Possible Strategies: Beyond All Reason doesn't limit you in terms of resources or the size of your army. Want to humiliate your enemies by disarming them within a few precise early strikes? No problem. Prefer to build up and obliterate them with a thousand bombers? We got you covered! Immerse yourself in a world where the only real limitation to the scale of the battle is what your CPU can handle! 400+ Units Unique and with a Purpose: Each and every unit in the game has a role to fill. Mix-and-match units to create infinite possible tactics. Experiment with your own combinations and show off the new strategies you develop in battle.
