Hazardous Materials - Incident at XJ 86 [R2] file

Medium-sized level (about 20 minutes) that I created for a creative contest. Sam decides to inspect the complex for testing experimental weapons, during his "visit" to the lunar base. In addition to the new level in the lunar/laboratory style, there are 4 "new" types of weapons, created on the basis of the original sprites. Also added some decorative graphics.
