Some Q&A About BioShock 2 (All credit goes to BloodThunder (twitch.tv/bl00d_thunder) for this FAQ):

Q: What's WR on BioShock 2? Where can I see all the PB times?
A: http://www.speedrun.com/bioshock

Q. Why do you play on Easy?
A. Playing on Normal/Hard only makes the speedrun more tedious, and doesn't add any entertainment. Enemies become bullet sponges making the run more about gathering supplies rather than trying to go fast.

Q. Do you save or harvest Little Sisters/How much ADAM is gathered?
A. BioShock 2 forces you to interact with at least 4 little sisters, I harvest 3 and save 1. Harvesting 3 of the little sisters at specific points allow you to obtain certain plasmids/tonics with the extra adam that are beneficial in speeding up the run.

Q. What plasmids/tonics do you use?
A. I obtain the plasmids; Electrobolt, telekinesis, incinerate, decoy, scout and winter blast(upgraded to lv 3). I also get the tonics; sportsboost, drill power, drill lurker, keen observer and damage research.

Q. What do you use Scout for?

Q. What weapon upgrades do you get?
A. Drill damage increase.

Q. What are you doing with the radio messages? [DIARY SKIP]
A. A trick known as Diary Skipping allows me to bypass all the NPC dialogue in the level if I manage to play a diary message at the exact time a radio message begins to play. There is an alternative method for skipping individual messages by quicksaving/quickloading while a radio message is playing.

Q. Why don't use just melt the ice in Ryan's Amusement with an exploding barrel?
A. The Ice cannot be triggered to melt by any means until you actually obtain incinerate.

Q. Why do you use Decoy there in Pauper's Drop?
A. You want to use Decoy to keep a Brute that spawns there so you can freeze him. If you don't freeze him fast enough he will disappear.
You want to get the research from him, you want to keep him frozen and attack him to get it. After this you get Drill Dash, the best movement in the game.

Q. Why do you keep dying?
A. I'm doing what is known as death warping, meaning that I die in order to respawn at a certain area that makes for faster travel then walking. In some circumstances, it actually skips certain parts of the game.

Q. What's the Theater skip you are talking about?
A. It's the skip in Fontaine Futuristics that skips the fight in the Theater area. It's considered one of the hardest in the game to get used to at first. You want to set up a sign on top of a turret and use another turret to do the skip, as shown in this video: https://youtu.be/Luez47-8o3A?t=2m45s

Q. Why do you not fight the splicers in the final fight, and only use decoy?
A. The final fight is on a timer so it doesn't matter about killing the splicers. The next wave of enemies(brute and houdini splicers) won't spawn until the 3 leadhead splicers die, so it is more convenient to let the 3 leadhead splicers live.

Q. How much is that doggie in the window?
A. Tree-Fiddy!
