I don't know how much weirder it can get than some of the bosses in the Contra series, but all things considered, every soldier has to have his limit. Plus, there's always that adage about "getting too old" for some shit or another.
It's interesting to see a second mini-arc right after that Mega Man mini-arc. Apparently I really just didn't want to work on the main plotline.
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
