Universal Soldier is basically Turrican 2. Except they changed several bosses (for the worse, but they're tolerable), removed the shmup stages, and added in some new levels. Even if you've never played Turrican 2, you can tell which levels are new as they're not as good and somewhat generic. But they're not that bad, either.
Universal Soldier gets a bum rap because of the license and because Turrican fans are a bunch of purists. It's really not a bad game at all IMO.
