Contra 4 (2007) is largely a combined remake of the early NES and SNES Contra titles, featuring remixed music and vastly improved visuals utilizing both screens of the DS as if they were one contiguous screen.
Watch Bill Rizer embark on a new colorful adventure in the shirtless land, this time making even less sense than ever before. To quote the game's ending:
Whatever the truth may have been, it was lost to time as the invaders became a mere footnote in the pages of history. A footnote which read: they sure blew up good.
Amen.
