From the very beginning "Rush'n Attack" ("Green Beret" in Japan) perfectly exemplifies 1980's Konami arcade game design. It's mercilessly challenging, totally relentless, brilliantly simplistic, and intense. Rush'n Attack never takes a break from the action and you are constantly almost overwhelmed by enemies pouring onto the screen. There's never a moment's rest and your success is going to be completely dependent on your reflexes. As its American name kind of implies, your objective is to move right and attack without discretion. There are four levels total, and the game loops after they are all completed.
