Alien Autopsy is a minigame available to play in the Government Lab in The Sims 2. It can be played if your sim has a mummified alien in their inventory. They can be found by using the Metal Detector in the Desert.
It is one of the more difficult minigames and very risky, as if it goes wrong, the simoleons earned can decrease rapidly. For this reason, many players choose to just sell the mummified aliens at the Store, as the cash reward is acceptable anyway.
How to play[]
Alien organs bring top dollar! Find a mummified alien in the Desert and bring it back here for experimentation. Use the laser to carefully trace each organ so it can be removed and placed in the cooler. Remember, organs are fragile and only healthy specimens are worth big money. Watch out for alien parasites! Remove them with tweezers before they devour your precious commodity!
Gamebreaking Bug[]
Due to a bug in the handling of the pockets system, the Alien Autopsy table counts aliens that exist in empty pocket slots. This can occurr when your pockets are full, and the last item in your pockets in a mummified alien. When the game goes to remove the alien, it does not modify what the pocket contains, it only decrements the number of items you are holding. Because the empty slot is still assigned to be an alien, the table believes there is still an alien.
The unforuntate result of this is that if you play the game again and again, the table will begin making items in your pockets disappear, until there is nothing left. If you continue beyond that point, the stored value for number of active pocket slots will wrap down from 00 to FF, and any time after this happens, even if you save and reload the game, will cause the opening the pockets menu to completely crash the game.
There are two ways to fix this- without an Action Replay, you can attempt to play the Alien Autopsy game around 249 times, in an effort to get the pockets menu value back to a number between 0 and 6, or you can use the Pockets Anti-Corruption code from the Action Replay codes page. The latter option actually actively prevents this problem from happening at all.
