I Chose the Impossible

I Chose the Impossible is a secret PlayStation and PC-exclusive Achievement/Trophy in BioShock. The Trophy is gold.
==Requirements==
The player will have to finish the game on Survivor difficulty, without using the Vita-Chamber, which is where the player respawns when killed.
==Notes==
*The difficulty setting is chosen when starting a new game.
*The player will get this Achievement/Trophy the moment they finish the game.
*The player can turn on the "Disable Vita-Chamber" option in the Options menu, causing the game to end instead of resurrecting the player at a Vita-Chamber, giving the player the option to load a previous save or return to the main menu. If the player dies and the Vita-Chambers are not disabled, they will automatically use the Vita-Chamber, failing the Achievement/Trophy.
**The player does not have to turn on "Disable Vita-Chamber" to get the Achievement/Trophy, provided they don't die.
**Loading a previous save will not prevent the player from achieving this Achievement/Trophy.
***Do not load another save set to another difficulty, as doing this will change the difficulty globally and cause you to fail this Achievement/Trophy.
*Winning the game with New Game Plus will not count for this Achievement/Trophy.
*The player will get this Achievement/Trophy, along with Seriously Good at This, Brass Balls and A Man Chooses, if they haven't already achieved them.
*Changing the difficulty during a playthrough will fail the Achievement/Trophy.
==Strategy==
*Save the game a lot. Most players will die several times.
*It is recommended to skip fights with Big Daddies, as they can kill the player in a few hits. If the player chooses to fight a Big Daddy, one should be well prepared. Although killing a Big Daddy will guarantee the player ADAM, many Plasmids and Gene Tonics are found out in the open throughout the game.
**The Hephaestus level is the only level where the player has to kill Big Daddies (A Big daddy will attack the player in Proving Grounds, but it is not required to kill it to precede, although it is recommended).
**For strategies to kill the two Big Daddy types, see: Bouncer and Rosie.
*Max out research rewards as soon as possible, as they give bonus damages and rewards. The Research Camera is found in Neptune's Bounty.
*Use the Plasmids Enrage and Security Bullseye to divert enemies away from you.
*Use the Power to the People vending machines when found. 
*Hack everything. Having a hacked Security Bot as an ally can help the player in battle.
*While looting is recommended for supplies, exploring for the sake of exploring is not, as there is a lot that can kill the player. Save exploring for another run and get through the levels as fast as possible.
==Behind the Scenes==
*The Achievement/Trophy icon depicts a sad Grim Reaper.
*The name of the Achievement/Trophy refers to Andrew Ryan's quote heard while descending into Rapture during the game's first level.
