What a Painful World is a music track in Contra: Hard Corps. It plays briefly in only one instance; during the Game Over ending.
In the Missile stage, if one agrees to join Colonel Bahamut, the screen fades to black, followed by his laugh. This track then plays as an image of Bahamut and any character(s) that joined him, is displayed amongst a burning landscape of ruins around them.
The name of the track may either reference Bahamut's devastating takeover of the entire world, or may reference the scenario of this ending leading the player to a Game Over, forcing them to either restart the stage with their previous equipment lost or simply end the game.
