Ray Crisis - Playstation - Encroachment 100% End 

RayStorm too had a bad ending, if you play 13 Ships mode (not available in Android). Thunder Force 5 and 6 also have bad endings.

Late reply This ending is where all every living soul human killed by con-human and altered the environment the planet earth, so the total results of war between human-con-human is every living soul human are annihilated and con-human, created from supercomputer being out of control are winning and mother nature aka earth is also died by altering the planet and cannot be stop forever because the supercomputer keep mass producing cloning humans maybe like trillion into quadrillion and then infinite cloning and then BOOM no more living soul humans anymore but only the dozens soulless of con-human so you will say RIP good earth and mother nature

@ The Creator RayForce only happens in the good ending, they don't even get a chance to do it here

@ The Creator Misread, sorry

Con-human destroys the 2% population of humanity left, and Rayforce never happens I guess.

​@TheCrimsonManthe AC port of RayCrisis ending shared majority in the PS1 port.
