The Game Walkthrough

You will find that sometime during the second level, you receive a camera. Take pictures of the "Splicers" at every avaliable oppurtunity, even if they are dead. This is because over time if you take photos of a specific type of "Splicer" you gain an advantage over that "Splicer", for example, you may do more damage against them. Furthermore you gain achievements in the Xbox 360 Version of the game for taking a certain amount of pictures.

This is the first major boss that you will encounter. If you are on medium difficulty or below, you should not find him too hard. However, on Hard, unless you have a effective stratergy, he will wipe the floor with you. Here are some tips:

- Hack the Healing Stations - When he has low health, he will attempt to heal at a nearby healing station. To solve this, simply hack it. This will cause the good doctor to loose some health as well as rendering him immobile for a while.

- You can use telekinesis to take one of the nearby oxygen tanks and throwing it at him - This can cause a substantial amount of damage and also render him immobile for a short period of time.

- Keep Moving - If you do not keep moving, he will simply shoot you and hit you with his powerful Tommy-gun and you will find yourself being revived in a Vita Chamber if you're not careful.

Finally. The hardest way. The most boring and time consuming way. If you have no decent items, no armor-piercing bullets and no money, then here is a way to defeat the daddies. Quite Simply, find the daddy, and hit it with your wrench. As much as you can. Until you die. Once you have died, you will be revived in a nearby Vita Chamber. Simply find the Daddy again, and carry on where you left off. This method is time consuming, as well as boring as hell, but it does get the job done. Eventually. Note, this is very ineffective on Hard difficulty.

Now, the most expensive way to kill Big Daddies. If you have a LOT of armor piercing bullets, about 80, then simply shoot the Daddy, preferably while your quite far away, and eventually it will kill it. This does take a while, so it is recommended to either freeze or shock your enemy, especially if it gets close to you.

If you have already received the crossbow from the artist about half-way through the game and you have some trap bolts, there is a very simple way to deal with the big daddies - Simply shoot the trap bolts at the Big Daddy, and you will find that they do a significant amount of damage. After you have shot the bolt you may want to move a bit because if you get a direct hit and you do not move, you will be hurt as well.

You will find that unless you are on the easy difficulty, Big Daddies are actually rather hard to kill. Here is one stratergy that can be employed against them:

- Use Proximity Mines: Attack a Big Daddy with a long ranged weapon, just so it is following you. Then, run away from it, dropping proximity mines as you go. If you need time to reload, you could try shocking or freezing it to buy you some time.

Choose your Plasmids wisely - Gene machines where you can exchange your Plasmids are rare. Match your chosen Plasmids to your environment, for example, when you are in the icy area, you must have the inferno Plasmid, without it, you will no get very far.

In Bioshock, you can gain money from either defeated enemies, or containers/safes etc.
You will find that if you manage to own $500 in the game, your wallet will not be able to carry any more. If this happens to you, simple find the nearest vending machine an "invest" in some items - I would spend no more that $200.

- Use the Vita Chambers! If you die anywhere in Rapture (excluding the final boss battle), you will be revived and brought back to life in a Vita Chamber. This can be hugely beneficial - If you are trying to kill a Big Daddy, but finding it difficult, simply attack it until it kills you, find it again and carry on attacking it - Do not fear dieing.

- Save the Little Sisters! You may feel inclined to harvest the Little Sisters throughout the game, however it is much more beneficial to save them. You ask why. Whereas you receive less Adam for rescuing the Little Sisters, for every 3 you save, you will receive a gift from the little sisters. This will comprise of 200-400 Adam and also various rare ammunition and items.

Here are some simple tips that will help you on your way throughout Rapture:

- Use the Wrench! The Wrench, the first weapon that you receive is actually rather powerful, considering it is the first weapon in the game. Especially since ammunition is rather scarce throughout the game, the wrench makes an excellent alternative to guns. Furthermore there are several tonics situated throughout the game that can enhance the power of the wrench.
