Bests & Worsts Reviews from Amazon

Impressive. You have 30 levels, fully free movement and an equipment store that offers improved ammo, weapons etc at reasonable prices. Since you can replay levels, I see no reason to spend real money, you don't even have to grind much. Radar and binoculars help spotting animals. They can take quite a few hits, you can't snipe them; instead, once your aim is true keep pressing the button for rapid fire. I only played two levels so far, but since they sell medkits, I expect animals in higher levels to be dangerous.
