  • Unlock The Endings

    To get the endings you need to play the game in Normal mode, and either get a low rank to end the game prematurely on Stage 5 or 6, or get a high rank to move to the next stage. Unlike what most information online says, there is no additional or alternative ending for beating the last mission with an "S Rank". You do get an extra congratulatory message in the ending for doing so, and you unlock a joke FMV in the theater menu.

    UnlockableHow to Unlock
    Ending (Easy)Finish Stage 5 on Easy Mode.
    Ending 1 (Normal)Finish Stage 5 with a B or C Total Rank.
    Ending 2 (Normal)Finish Stage 6 with a B or C Total Rank.
    Ending 3 (Normal)Finish Stage 7 (if you finish with an "S Rank", you'll get an additional congratulatory message).

  • Unlock a Hilarious Movie in Theater

    Complete the game on ''Normal'' difficulty with an ''S'' ranking. This is very tough to do. Once you received an ''S'' ranking, the hilarious movie will be available in ''Theater'' mode in ''Etc'' mode. View the movie to see something really hilarious.
