User Rating: 9.5 | Command & Conquer: Red Alert 2 PC
Red Alert 2 takes place in the "battlegrounds of alternate history." The premisice of the game is that Russia invades the U.S. The story is hillariously conveyed through live action cut scenes like the CnC games before it.
Red Alert 2 is your tipicall RTS game where you build a base, build up a massive army, and then utterly destroy your enemy off the face of the earth.
It plays much like the original Red Alert except with new units like mutant squids and dolfins, and then there's Yuri. A crazy man who takes over the brains of other people, controlling them.
Both sides, Soviets and the Allies are very ballanced. The Soviets have better low tear units while the Allies have better high tear units, although its pretty even. Each country in the game has it's own special, unit, structure or ability. The U.S can drop parratroopers, while Cuba has terrorists who blow themselves up.
The game features no long technology trees or upgrading, in fact, there are no upgrades at all. You gain acces to new units by building certain expensive buildings. This makes each online match go relitively quikley because it's easy to rush. When you get bored of playing against peoplem you can play co- op with them in a short "campain." Sadly, each campain is merely a online match with you two vs the comp, no story, no special base to attack, nothing. But, you probaly won't venture there.
Overall the game is a superb, highly addictive game that will keep you playing for a long time to come.
