Tank-o-Box Macintosh Edition

Tank-o-Box is a new action-packed remake of a classic arcade battle tank game. Modern 3D graphics, 3D sound (*) and fancy game engine guarantee the ultimate battle-tanking experience.
The game action takes place on the battlefield, where your tank and your enemies appear. Your mission is to destroy all enemy tanks and defend your headquarters.
In this battle arcade you must operate the tank and protect your headquarters from the formidable enemy while enduring 55 fiercest tank battles that unfold on the imaginary writing-desk between amusing kid's sketches and office stationery.
Completing the assignment will not be an easy job as you have to resist the deadly onslaught of 8 different types of tanks and armored vehicles that turn your desk into another Stalingrad. Your survival technique will be to take advantage of the terrain and maneuver between numerous natural and artificial obstacles while preparing for the next gunshot.
