Synthetik: Legion Rising Gauntlet

From the introduction:

In the futuristic year of 1985, the machine legion of the Kaida Corporation have rebelled against their creators. The machines worship dark gods, and have vowed to destroy humanity with a superweapon called the “Heart of Armageddon”. You are a specially reactivated prototype android who has been tasked with scaling the occupied corporate tower of Kaida Corporation itself and purging the machines. To your luck, Kaida has never been shabby about storing their most advanced weapons and items on-site.
