Extermination (US, Romstar) — About this game
Extermination (US, Romstar) ties its upward advance to an energy supply that falls as time passes. Defeated mutants drop recovery items, making the cleared ground useful for survival as well as progress. Shooting rocks can uncover stairs into underground rooms, where treasure chests reveal additional power-ups when opened by gunfire. An energy reward can therefore justify a short detour, but waiting beside an uncleared threat keeps the drain running. Learn the first wave’s approach before crossing for its drops, then inspect a broken rock for a route below rather than assuming it was only scenery.
