Jaz: Repetitive it may be, but this is very fast, highly challenging and great fun. It's still brill after all these years and makes even new games like G-Loc and Afterburner III look very cack indeed. I wouldn't change the marks at all.
Rich: Well, call me very old fashioned, but I still play this game and it is still utterly awesome. In fact, a couple of months ago, my mate showed it to one of the UK's top programmers (who hadn't seen it before) and he was amazed! If you're after a decent shooter I highly recommend this fab game.
