Atari's "
Tempest 4000" is on sale for 50% of thru Apr 12, 2020 on the Steam platform.
Just bought it and it does remind me of tempest. I miss the spinner tho.

That said; its probably barely worth the 10buck price... seems to be a rather poor port to the PCs. Poor / non existant "configure controls" screen. And it defiantly should have a seizure inducing/warning.

Pretty good sound track... but expect to need a game pad of some type to really enjoy this. I couldn't figure out how to control via keyboard.
