Run-and-gun action where you mow down cyborgs and mutants across branching levels. Set in 2641, three years after alien invasions left Earth a mess—stolen alien cells from a military lab kick off a conspiracy involving a rogue major and bioweapons. Pick one of four playable characters, each with different abilities, then blast through ten stages loaded with screen-filling bosses. You'll find homing guns, crush cannons, needle lasers, and mine setters as you go. The path splits multiple times based on your choices, leading to different endings. Expect relentless enemy waves, precise jumps over instant-death pits, and bosses that demand pattern recognition. This Genesis entry in the franchise doesn't ease up—if you're used to infinite continues, brace yourself.
