Oretachi Gēsen Zoku is a series of 19 emulated arcade machine game titles from the 80s and 90s for PlayStation 2 published by Hamster and only available in Japan.

The universe teeters on the brink of total annihilation at the hands of the vile alien warmonger, Red Falcon. Earth's only hope rests with you, a courageous member of the Special Forces elite commando squad. Your mission: Battle deep into the deadly Amazon jungle, where the Red Falcon and his galactic henchmen have transformed ancient Mayan temples into awesome monuments dedicated to mass destruction. A multitude of weapons, from rapid-fire machine guns to high-tech lasers are at your disposal as you sweat blood, fighting past 3-D mazes, underground security systems, and tropical forests surrounded by giant waterfalls and alien cannons. This is the ultimate test for the ultimate guerilla warrior. And if you survive, Earth survives!
