It's all right but facing the same craft during each misson gets boring, also the designer made the ships too close to each other so when it fires, it hits friendly, so it keeps firing at friendly craft, usually your misson goals!
good misson. just two things keeps it from making it into a 5. 1.The fighters was easy to destroy on hard. 2. the Capitial ship never fires back. but from that a good misson.
