With the base levels out of the way, the game starts getting harder as we come to level 5. One thing you wouldn't expect to see on a tropical mountain is a snow field, but that's what the scenery is here. This level introduces the enemies who use big stand-up guns platforms, and also has pill-shaped grenades that come from the background, and enemy tanks with spikes on the front of them.

There are many hard parts in level 5 such as this one here.

These tanks are very hard for first time players, if you don't have your scatter gun with you. Run all the way to the left, turn around slightly and fire as fast as possible before the tank has a chance to advance.

This boss is pathetic. Just get under it and fire away, if you fire fairly fast it should be dead before it has a chance to disappear and reappear again, or hit you with any of its projectiles.
