Anyone who has played the old C&C strategy games will feel right at home. You'll start a match, gather resources, build yourself a base, create an army, then go out to demolish the competition with a cavalcade of tanks, troops, and aircraft. The controls are fairly standard for an RTS, but the developers are making an effort to create an interface and mechanics easy enough for beginners to get the hang of. At the same time, there seems to be plenty of complexity with unit upgrades and determining efficient build orders to keep the veterans satisfied.
In addition to sending your units to victory or death, developing your base quickly is a huge part of winning a battle. Standard structures can be upgraded, allowing you to build advanced structures, giving you better units, and more powerful armies. From our playtime with the game, it seemed that the more aggressive player took control of the battle more easily than a player that turtled behind base defenses.
