Game started out as an interesting MotherLoad variant, but just got dull. While the missions gave a greater sense of purpose, they conflicted uncomfortably with mining for money; in fact, there was literally no need to sell ore, since the jobs paid out so much. There was one that asked for sand.... and then we didn't get anything else special. The leap from 2nd best cooling system to best was way, way too high. I was hoping for more, but it stayed at the introductory level, and that's why I gave it two stars.
