Hints

Defeating the Strider

After you climb the ladder and get up on the platform, you will notice a box containing rockets behind one of the metal sheets. If you get on it, you will be able to see a small part of the Strider but it will not see you. Observe its pattern of movement and fire a rocket just before it takes a new position. You will not miss by doing this. Keep firing at it until your cover breaks down. Until then you can easily score about five hits on it without losing any life. Then, move behind another metal sheet and finish off the Strider easily with one or two hits.
