One correction for the review. The playstation version of Tempest, I think it was Tempest X3 or something is nothing to do with llamasoft. Jeff Minter was quite unhappy about that, didn't like the blurry vectors or the gameplay.
I have tried Tempest 4000 and there does seem to be built in momentum on your claw when you move around the web. I do not remember that in the Jag version of Tempest 2000 which I played in an emulator
