The idea of the game is to kill all the enemies climbing up the web and progress onto new webs. You have got unlimited ammo for your laser but only 1 megablast per level. On each level you also only have a set number of jumps. At the end of each level bonuses are given for remaining jumps and megablast.

 The following controls are used to play TEMPEST 1000.

	fire
	jump
	left
	right
	megablast
	start
	quit
