This is one of the best Real time strategy games currently available. The campaign consists out of small missions where you don't have to build a base. You get a lot of loot while doing the missions and you can turn the loot that you don't need into experience. The story is great and if you have a friend who also has this game you can do the campaign in co-op. Beside the campaign there are 2 more modes that you can play: Multi-player and The last stand. In the multi-player you can do 1vs1, 2vs2 and 3vs3 and you really need to work together to crush the enemy completely. The last stand is a survival mode where 20 waves come after you and 2 others. The difficulty will increase with every wave and to get a really high score teamwork is necessary. In my opinion this is one of the best real time strategy games of the last few years.
