You are Zed, half man, half cyborg.
The one-man battalion with a human heart and a computer brain. Can you blast your way alone through 27 combat zones to free the desperate people of planet Altile from the evil invader Xur? Xur has seized the weather control station; it's freezing cold and the people have fled underground.
He knows you've landed. No turning back. You must recover an arsenal of 12 different weapons and 6 hidden powers on Altile.
Megaton bombs, life jackets, hyper missiles, super boots, crossfire, super bombs, energy pods, life pods, power balls... Master each one to save yourself from a continuous barrage of 20 deadly enemies.
Wisps, Wanes, Tracers, Strinkers, Skraugs, the Globula, Gholem, Viripides... They're mean, they're ugly and they're after you. Flying. Dive-bombing. Twisting. Grabbing.
Find the keys, or you're stuck in a combat zone forever. Find the hidden chalice and be saved from eternal doom.
Hit the switch. It's war!
