First. you can only do one in app purchase ”ONE”
Second. it will pop up a add saying there is a "problem in the game please research null to fix the problem" this will happen every time you open this app. That will pop up two or seven times.
Third. some times it glitches.
Fourth. Why two stars? Because it is sometimes fun to play but it is very realistic violence and a lot of bleeding and blood also on the single player one. When you kill a monster a lot of blood spills and the guts fly out.
Fifth. Fix the in app purchase problem.
