Opening Weekend: Varmint Season is a varmint hunting simulator, from the makers of the 3D Hunting series. Using a 3D engine players move around environments in lush northern Oregon, Idaho canyons, and Pennsylvania, in pursuit of varmints. Weapons include .22 and .25 rifles, a shotgun, a wrist rocket, and a blowgun. The game features an advanced AI where cats become more intelligent and skittish as your skill increases; they are able to see you, hear you, and even smell you, and will attack when provoked. Prey includes rabbits, rats, raccoons, coyotes, badgers, opossums, squirrels and mountain lions.
