Single player mode is too short.
While this is a good tower offense game with cool graphics,single player mode has 14stages or so, and you can finish it less than 8hours.
I don't think this game worths 15bucks, just wait for sale.
All About Tower Offense vs. Tower Defense
Anomaly 2 is a sequel to the critically acclaimed Anomaly Warzone Earth. Maintaining the core elements of the original, Anomaly 2 adds new features to the single-player campaign and finally puts your skills to a test in a completely unique experience: the dynamic tower defense vs. tower offense multiplayer mode!
In the years following the invasion of Earth in 2018, the planet is overrun by alien machines. Humankind is on the verge of extinction. Banded together in huge convoys, they search the frozen tundra for food and supplies. Since the war, the roles have been reversed: now our species seems to be the Anomaly on a machine-controlled planet. Your convoy, Commander, is called Yukon.
