Commando 2

Several levels await your super-tough Commando in this vertical scrolling
game. Armed with only a standard rifle and a few grenades you must take on
hordes of Nazis. Some are wandering around in the open, while others have
picked out hiding places, which you must approach from certain angles. Trees,
rivers and bridges create a varied combat-like terrain and must be
incorporated into your thinking. Extra grenades can be collected, and will
definitely be required, as they allow you to kill from distance and thus avoid
some enemy shots.
