Deus Ex: Invisible War Cheats

To unlock a secret Wrap Party ending, do the following:

1. At Liberty Island, go to the UNATCO map. You will see a UNATCO Flag in the first room. Pick it up.
2. Take the flag to Manderly's office, and go into the bathroom. Drop the flag in the bathroom, then flush the toilet.
3. You'll then be transported to a hilarious party ending! Be sure to check out the Datacubes for even more hilarity.

Note: Who is at the party depends on what characters you kill throughout the game.
