Frontline (COLECOVISION CV)

Front Line is a vertical scrolling action game. Your mission is to infiltrate enemy territory and destroy their fortress. To reach the fortress, you will have to fight your way through varied and dangerous terrain. Jungles, deserts, brush, and rocks slow your progress, and each area has plenty of enemy fighters and tanks trying to stop you. To help you overcome these obstacles, you are armed with a machine gun and grenades; at certain points in the game, you may even come across an abandoned tank that you can control to increase your chances of survival. When you reach the end of the level and successfully destroy the fortress, the game will repeat at a higher difficulty level. The gameplay is for one or two players, and four different skill levels are available.
