Obliterator is a bit of a corker from Psygnosis. It's a mappers delight, featuring endless corridors packed with maurauding aliens of various sorts, plus guns and components that you have to pick up to complete your mission.
Your task is to escape an alien infested space craft before it blows up - a task made harder because you have to rebuild your shuttle from scattered components before you do so. Your largish sprite lollops around the ship, going up ladders or through teleports as the mood takes him. Some of the backgrounds and monsters are rather well designed - as they were on the spectacular 16 bit versions - but the game has the same faults: slightly jerky animation and limited scrolling.
Not only that, but you soon get the feeling that there's not very much to do except keep running around blowing those muthas into next week. I don't know about you, but I found this tends to pall after a while. Once you've completed the game you're unlikely to come back for afters.
What a shame, because it's well packaged, looks quite good and the unusual control system works very well once you've got used to it.
Looks better than it tastes. An uninspired shoot-'em-up.
