The Fall of Nemesis: Clash of the Kaijujin (or "The Fall of Nemesis") is a kaiju fighting game created by Sunstone Games. It is the second game in the Colossal Kaiju Combat franchise, as well as the first commercial release.
"The Kaijujin have a new champion - Nemesis - and they have organized a tournament to see how well she fares against a collection of Earth's mightiest kaiju! (Plus a few uninvited guests…) competition will be fierce both on and off the field - and ultimately Nemesis will fall!"
Originally, there was a reward in the Colossal Kaiju Combat OUYA Kickstarter in which the person who pledged $10,000 would have their original monster be the 12th monster in The Fall of Nemesis: Clash of the Kaijujin. Unfortunately, since the kickstarter failed, the 12th monster was scrapped.
