He has had the Uber Ending 'under construction' while still published since 2003. FOUR YEARS! If it was that minor, he would have finished it in a few weeks. The endings in Wal*Mart are not minor at all, as they all provide closure:
Here are the endings, worst to best.
Death Ending: You get shot by a terrorist. Easy
Surrender: You surrender to the terrorists during the introduction
Brown Stains: You sh*t your pants in the introduction
Sneak Out: You sneak out through a loading bay and never go back
Remote Car Bomb: The 'Normal' ending, you set off a bomb, blocking the terrorist's access to the hostages while they escape. You get no recognition at all.
Uber Ending: There is a page stating that the player has found the key to the Uber Ending, however it was never completed.
Seriously Fleshy, do a tally on who wants the ending finished.
