Quite a seriously old side-view scrolling shooter this, but one which provoked enormous interest for a while after it first came out. It's not hard to see why. But I'll tell you anyway.
The scenario is essentially violent, which is always a good selling point. This time you're a Green Bert with all that that entails, namely a mission to slash and shoot your way through four levels against overwhelming odds. The odds consist of enemy soldiers armed with assorted weapons, some of which you can nick for your own use. Each level is arranged differently and packed with, er, action, and the backgrounds and sprites are beautifully drawn. My only criticism (I like to find at least one each time) is that it's a bit difficult - there's no gradual build up or anything.
