Heavy Tank

Heavy Tank is an action game where you must save the world from the Secret Force invasion. The tank can only move left and right since it's a side-scrolling game. The game has 19 levels, along with 2 game modes (Mission and Survival). In Mission mode, you must blast through countless enemies, and in the end, defeat a boss. After defeating a boss, you are going to visit the armory, where you can upgrade your tank with various weapons and power-ups. After going through nine bosses, you'll have to go all the way back to the start and destroy the same nine bosses (upgraded versions), until the final boss. In Survival mode, you'll have to survive through a never-ending wave of enemies, until you have been eliminated. In time, the waves become more crowded with enemies, adding more difficulty to it.
