Pros: Nice art and graphics. Entertaining, humorous story that lampoons a lot of old science fiction. Cons: The controls could be better. No real free roam. Autosaves override the one you generated initially and there is no way to trace back to the final mission, this might be due to the game's age, but it robs you of flexibility, especially if the saucer needs upgrades. The saucer itself was pretty horrible to fly. For a humorous shooter I would have preferred less sneaking and more options to just shoot your way through most tragets. The only actually difficult segment is the boss fight at the end, replaying stealth segments can be annoying, though.
