Additionally, there are 10 secret achievements, all of which are currently unknown.
The following works with both the Crossbow and the Grenade Launcher. While shooting either, you can rapidly reload by pressing the left trigger, then quickly after pressing the right trigger. This will allow you to start shooting without having to wait longer (several seconds) for your weapon to reload. This is especially useful against powerful enemies like Big Daddies.
: Play to the end of the game on Easy or Normal and get Atlas down to his last jar of Adam. Pause, go to Options and change the difficulty to Hard. Finish Atlas off and you should get the Achievements. *** Don't die if you want Brass Balls.
If you have Trap Bolts for your Crossbow, you can execute this technique to kill Big Daddies easily. Give yourself about 20 feet and shoot your Trap Bolts so they hang between you and the location of the Big Daddy you want to kill. Then shoot a round with another weapon at the Big Daddy to anger it so it comes towards you. It will stumble across the Trap Bolts you've shot and die, since it only takes 2 of them to take one down.
Simply use Telekinesis on one to hurl a body at others. This method should result in a one-hit kill and is especially useful against higher-level Splicers.
Try using Electric Gel in the Chemical Thrower. It takes about 3/4 of a tank, but the Big Daddy will not be able to move as you shoot and kill him.
We are always looking for more cheats for BioShock. As far as that goes we are also looking for hints, tips, easter eggs, glitches, etc. So please cheat back often to find game cheats for BioShock.
While you can buy health packs at health stations for $10, you can get them for free by simply smashing the machines with your wrench. After a few hits, between 1-3 health packs should lie on the floor for you to grab.
: There are 2 possible endings for BioShock that depend on how you treated little sisters throughout the game. If you choose to "harvest" more than one little sister, you will get the bad BioShock ending. If, however, you "harvest" no more than one little sister but "rescue" the others, you will get the good BioShock ending.
