Thunderground is a game for the Atari 2600.you Play as a Tank digging underground,trying to hit these strange orbs,and doing so will give you 50 points.and shooting all six will take you to the next level.your only enemies are,of course,enemy tanks,who will come from the top either sides of the screen and will try to shoot you.If they do,you explode.However,if you shoot them,you get 50 points.the number of the level is located at the bottom of the screen so you know where you are.the controls are simple.control pad moves you around and pushes dirt out of the way at the same time.pressing the space bar allows you to fire your cannon.every once in awhile,you'll find these mysterious items hidden in the dirt.Every time you grab them,they turn your tank blue.one problem is that at the bottom screen,you can see 3 an enemy tank slowly edging it's way towards 3 other orange tanks,in other words,your tanks.if he gets to close,you get this alert sound,meaning for you hurry and shoot those orbs.And if you don't shoot them all,then he runs right into you,and you only get three lives.As you progress through,like any other game,the difficulty increases which is perfectly normal.In conclusion,the game is fun and addicting.Not to easy,not to hard,easy-to-understand concept,easy controls,and fairly good graphics.
