Assault Suit Valken
Assault Suits Valken is the Japanese version of Cybernator, a game that Konami brought over to America. The game is a sidescrolling shooter similar to Contra, but here you pilot a huge Mech named [s]Gundam[s] Valken. The main difference between this version and the US one is the story - a lot of things were removed by Konami for no reason, and the game paused itself while you received instructions during a mission in the US version. Valken doesnt do that, which may be a disadvantage - particularly against the last boss, who you cant attack until he shuts up. But he can attack you! Yep, unfair, but thats life.
