Probotector is Contra. (I think like how Super Mario Bros. 2 is Doki Doki Panic. Not related, but Contra Force isn't a Contra game.)
I guess it should be called
Dolled Up Installment? Careful with the link.
It was changed because of some European law about depiction of human killing humans or something. It was like that all the way to Contra 4 (you can choose to play as one of the Probotectors. :3)
Long explanation aside, I THINK I can do Probotector 1 and 2. My only beef: I raeg on 50FPS.
