Evolution is the topic here. You build up from the neanderthals to a great power with laser weapons. In this case, you go 1:1 with your opponent to develop and evolve, depending on difficulty. It starts on the left side of the field and your opponent is on the right. In the middle, or depending on your progress, speed and strength, the computer players can be encountered. You can select various towers and buy units in exchange for your money. You get money when an enemy troop is destroyed. In addition you get EXP which can be used for evolution. More war games also for your mobile phone or tablet.
