Game: Contra (1987)

At first glance, the muscle-bound soldiers of Contra thought they were only dealing with rebels, militia troops and mercenaries. But, after digging deeper in this classic series, the two commandos discover that it is something from a much farther land than just overseas. Red Falcon waits, burrowed deep into its command center. The alien overlord hurls alien warriors, electric fields and more as you dare to reach the lone nerve center which make Red what he (or it) is. Thirty men, anyone?
