Plutos is a vertically-scrolling space blast strongly reminiscent of the arcade game Earth Force. The graphics are small but atmospheric, and while it's easy to start with, it gets very challenging a few levels in.

That's about all there is to say about it really, except that it's very playable and pretty addictive. I really like it, and while it undoubtedly shows its age, the gameplay is timeless. (In fact, in pure gameplay terms, I think this is a better game than the legendary Xenon 2).

After Quantox, Plutos is probably the best game in this range, and is well worth getting however much money you've got.
