Chopper 

Chopper is a fun action game for Mac filled with a wide range of missions and various obstacles. Even though the application doesn't provide you with impressive graphics, its addictive gameplay and unique levels can keep you in front of your PC for hours.

The program offers you plenty of game options to help you enjoy your gaming experience. You can choose between various display profiles (for example, 640x480, 800x600, etc.), adjust sound and music volumes, and opt for the proper texture resolution.

Your tasks change from one level to another while your main goal, which is to maneuver a helicopter, remains the same. The game provides you numerous civilian rescue assignments, but during these missions you can eliminate enemies for extra points and increase your final score.

Nevertheless, Chopper comes with plenty of flaws. The app doesn't let you save progress, doesn't allow you to replay previous levels, and plays repetitive music.

Cutting a long story short, Chopper is an entertaining game that offers you plenty of challenging levels and is free of charge. And even though it brings several disadvantages, I still think you should give this app a try.
