I think best game in armor games is Zombotron 2 becasue it's fun it's long and it's EPIC Next one is bit dunegon becasue it's never ending game and get harder every level and you can find very cool stuff.
It's pretty much the same as the first, so I don't like it much. It's not really long. I've played games that have a good story, have tons of weapons, and are really long.
