The war between aliens and humans has never taken place in reality but it has never ceased to take place in online games. That is what happens even here in this particular online game. However, this time you are going to be playing the role of an alien character that you get to choose at the start of the game. Use the weapons and your abilities to blast off all the human army units in order to defend your position. As an alien, you will be able to use various items to keep improving your weapons and your skills in order to be ready to face the increasingly powerful human attackers.
