Revision as of 13:31, 30 June 2014

If a trick applies to only some versions of the game, note which ones that is.

General

• Straferunning: just like in Doom, straferunning is faster than normal running. Also works under water.
• Key/wall glitch: if there's a lock on the other side of the wall (like in mission 2, the orange and red doors), you can unlock it through the wall
• Wall/window grab: it is sometimes possible to grab items/push buttons/pull levers through the wall. I haven't found a good spot to use it yet. It is also possible to attack someone with your sword through a thin wall.
• Crate stacking: stack crates to get somewhere you couldn't get before. You won't run any slower with a crate in your arms, so you can lug it around wherever you go until you reach an obstacle. You can't have your weapon equipped while carrying stuff though.
• Slowfall potions: they'll let you fall slower, but they also slow you down on the ground. If you're worried about the damage when making several long falls (without slowfall potions), put those healing potions to use. You can jump higher than normal using a slowfall potion. If you're airborne while you quaff one, you will keep up your velocity. ALSO, when you're underwater you can drink one to suddenly increase your buoyancy by a lot. The deeper down you were the more speed you'll be able to accumulate by the time you hit the surface. You might be able to reach a ledge that you otherwise couldn't this way.
• Speed potions: they'll let you run at twice the speed for about 9 seconds. So if you take 10 seconds to get one, you're wasting time.
• Soft drop: if you drop down from a ledge while crouched, you won't make any noise. This even works on tile and metal. The exception is when you take damage, Garett will say *humpf*.
• Glass breaking: pretty obvious, but you can break glass with your weapons or by jumping onto it (only works in v.1.18?)(like in mission 2 on the roof).
• Door blocking: you can block doors from closing by placing an object next to it. This comes in handy in a mission in Thief 1, I don't know if it is usable in Thief 2.
• You run slower with your sword equipped.
• Frogbeasting/bodyboarding: You can break your fall by jumping onto people, bots, monsters and bodies. When frogbeast eggs are available, you can use them to spawn a frog directly beneath you that will break your fall. Be careful though, you can still take some damage. Frogbeasting works best with 2 or more in your inventory; trying with only 1 in your inventory is very risky, as it doesn't break on Garrett.
• Elevatoring: you can climb up by dropping flares or scouting orbs on top of your head. If you don't have any flares left when dropping a flare, it will fall right through you, so you need at least two. Same goes for orbs. It works best when using the drop button, instead of tossing scout orbs directly above.
• Forcing open a door: there are several ways to force open a locked wooden door: four overhead swings or 10 slashes with your sword, 2 fire arrows, 2 frogbeasts, 1 mine or 1 well-placed cannon ball will all work. Some doors with a metal texture are actually wooden doors, examples of this are the front door of Angelwatch and the door to the office in the basecamp in Kidnap. Metal doors will open up using mines or fire arrows, but frogs don't work. This works in the Sold Out version of the game, there are other versions in which it doesn't work.
• Elevator Call Shots: Like in Shipping and Receiving, you can use arrows (broadhead, fire, gas, noisemaker and rope arrows all work) to hit the call buttons from a distance in other missions too. Useful in Soulforge at least.
• Speed boosts can be gained from landing on sloping surfaces, and even more speed can be had when jumping again as soon as you land on the slope.

Guards

• You can run faster than they can, especially when you're straferunning.
• The behaviour of guards isn't affected by items. For example: throw a burning flare in their face, they don't notice. Block their way with crates, they don't adjust their path or come up with a solution.
• Guards can't open a locked door if they haven't got the key for it.
• Guards have to be really close to sense you presence when your fully invisible, and they also have to be really close to hit you with their sword/hammer/mace.
• Guards don't climb ladders, jump, climb objects or fall down in order to chase you.
• Guards can't be pickpocketed when they're alert of your presence (chasing you or searching for you).
• Unlike civilians, guards can't be knocked out with the blackjack if they're aware of you. (In v.1.07 they can, just get behind them first)
• To kill a guard fast: throw 2 frogbeast eggs in his face or do an overhead swing and two sideswings in quick succession.
• Turn on auto body search to quickly grab the key off a corpse, no chance of accidentally picking up the corpse. Might wanna turn this off on Kidnap.
• Even while you're carrying someone, guards can't keep up with you. Take advantage of this in Kidnap.

The Mechanist Children

• Mechbeasts and watchers are temporarily blinded by a flash bomb.
• Combat bots can be distracted with noisemaker arrows (or other sources of sound).
• Combat bots can be destroyed with a single fire arrow if they're unaware of you, though not consistently. They can also be destroyed with two frogbeasts while unalerted, though I prefer to throw three. They can also be disabled with a single gas arrow to the furnace, or two water arrows.
• Combat bots lead their target; spider bots and sentries do not.
• Sentries can see farther than watchers.
• Watchers can't see what's underneath them. Sentries also have a blind spot, roughly the 90 degrees behind them.

Mission-specific (but not category-specific) notes:

Running Interference

• You can blow the birdcall as soon as you start the mission. Don't do it too quickly or it will take about 20 seconds for Basso to go. Instead, use it when Basso has walked into place and leans back, he will then run off immediately.
• You can knock on Jenivere's door to alert her and cause her to run out of her room as if Basso had come to unlock it. You need to hit a spot around the top left corner. The noise the spot makes will be much quieter than normal.
• It is fastest to call Basso at the end of the mission after Jenivere has been alerted after hitting her door.

Shipping ... and Receiving

• You have to get to the office even if you already have the required loot.
• Most of the orange locks in building A can be opened from the other side of the wall. When a tutorial pops up telling you to use your lock picks (normal difficulty setting) you know you've highlighted the lock.
• In Gilver's office, you can grab the diamond without slashing down the banner.

Framed

• You don't have to go to the hall of records to get the code. It's always 4026.
• If you 'elevator' yourself up the buildings at the start, you can get up onto the wall. From there you are able to climb onto the roofs and go round counter-clockwise. Finally you'll be able to cross the moat using a slow-fall jump (drink immediately AFTER jumping). Traverse a section of the perimeter wall to access the courtyard.
• If you have access to the items, the faster new way of entering the front courtyard is using an invisibility potion to get to where the front sentries are unharassed and a slow-fall potion to jump high off and mantle the perimeter wall directly. Isn't 100% consistent?
• The switch to the gate (with the two archers next to it) can be reached from the outside. If exiting the police station via this route you don't have to open the gate; standing next to it is enough to complete the objective.
• The walls around the two outside courtyard areas at the main gates and side entrance have unfilled geometry that allow you to pass through if you needed to get from the one the other or on the perimeter wall for some reason. (observed in 1.07)

Ambush!

• Items in Garrett's stash can be picked up through the wall while it is going up.
• You have to get the gate key even if you have already passed the gate by going OOB (the gate can even be mantled).
• Speed boosting on the sloping streets will shave a few seconds off.

Eavesdropping

• You have to overhear the conversation even if you already have the required loot and made a wax impression of the key.
• You cannot run away from the door, and the key location will be different every time, unless you use a savegame.

First City Bank and Trust

• You don't have to go to the hall of records to get the vault number, even though your objectives say so. It's always 11.
• If you get stuck on the window leading to the basement, it's probably because the handle is blocking you. Hug the window frame to pass it. If that doesn't work, try closing and opening the window. The window is actually made of wood, so you can force it open.
• In version 1.07 you can force open the vault door with explosives, it will go right through the metal bar.

Blackmail

• The watchers at the start are attached to wooden beams that you can stick rope arrows in.

Trace the Courier

• Lt. Mosley and the pagan will stand in one place from time to time to check if they're being followed. Usually Mosley only does this once in the beginning, you can avoid this by exposing yourself a little bit, she will then skip this. Putting out torches in front of her (she doesn't have to see it happen) distracts her further and she won't stop at all.
• You can't get too far away from the letter, but when you have it in your inventory you can run around the whole map without failing the objective, at least until the pagan notices that the letter is missing.

Trail of Blood

• There is a speed potion above the second red gem (normal) that doesn't take too long to obtain.
• Speed boosting on the slopes in the beginning of the level, and at the start of the Maw is a good idea.
• Using a combination of a speed potion and a slowfall potion (can be picked up near the face portal) will skip a lot of time in the Maw by ramping up and over a large gap, grabbing the edge. This can be difficult to do consistently.

Life of the Party

• You don't have to activate the voice machine in Karras' office.
• One of the guards guarding the fort (with the merlons) has a red key that you can use to open the room with the scripture.
• You can climb onto the bank's roof from the east side and make your way south from there. When you've reached the end of the roof you need to crouch in order to get any further, there's an invisible ceiling.
• If fast enough, there is a guard that exits the room with the scripture, and you can open the door again as it's closing.

Precious Cargo

• There are two fire arrows at the beginning of the mission, sitting on a window sill, and can be used to blow open the door to the freezer if none were purchased.

Kidnap

• Speed boosting on slopes is beneficial.

Casing the Joint

• When you blind an unalerted guard or servant with a flash bomb, it doesn't count as a 'confrontation'. (This DOES count as a confrontation in later versions of the game, at least on v1.21)
• You can exit the mansion by breaking a window. When you're on the east side of the second floor, positioning Garrett just on the outside of the window frame counts as 'exited'. You can climb into the mansion through some of the windows with unbreakable glass (with the metal grates), your position has to be just right and you'll go right through. (This might be earlier versions only, as it does not work in v1.21)
• It's possible, with the use of a crate, to elevator up to the second floor, and using a rope arrow, to gain access to the third floor.

Masks

• You can exit the mansion by breaking a window. When you're on the east side of the second floor, positioning Garett just on the outside of the window frame counts as 'exited'. You can climb into the mansion through some of the windows with unbreakable glass (with the metal grates), your position has to be just right and you'll go right through.

Sabotage at Soulforge

• You have to read the correspondence from Karras to brother Kelsus, even if you put the guiding beacon in place and all of the signal towers are using signal B.
• There are many places to frogbeast in this mission.
• It's possible to clip through the gate at the top of the beacon tower, and frob the lever to open the gate. Straferun into the gate, and as soon as contact is made, stop running, and lean into it.
• If your aim is good, it's possible to hit the elevator down button as you enter the pillar room. It's also possible to hit the down button at the next elevator (where an iron beast is guarding it).

Side notes

• In Thief 1, you accelerate after every bunnyjump. In Thief 2, you can keep up your velocity (speed potions) by bunnyhopping and you can increase it a little bit by hopping on a sloped surface (going downhill).
• The levels are different depending on the version you have. In principle any version that's the fastest can be accepted. Currently (April/'14) all the recent runs have been on 1.18. There are some glitches present on 1.07 that might help bring down the times even further. v.1.00 hasn't been explored at all. However, because the presently available versions are all 1.18, any runs on earlier versions will go under a different category. If the choice is arbitrary, or nearly so, you should run v.1.18.
• Fraps doesn't capture the menu screens because they are rendered with DirectDraw (it does record the audio in the menus). This isn't really necessary because you can see in-game what difficulty the level is by counting the health shields, but it does make determining the time more difficult, as the final time is displayed in the stats screen after the mission. So unless you use a recorder that can properly record DirectDraw (like this one), you have to time it manually. (Fraps has worked well with v1.21 of the game)
• If you use ZD Soft Game Recorder to capture, be sure to use a custom video size, or else it will default to 320x240 (or 640x480 if you capture at full screen size). This is because the menu size is 640x480. Of course this doesn't matter if you also use 640x480 in-game.
• On modern hardware, the Dark Engine might look like ass. There is a utility to fix this, ddfix. I'm not sure if it will be allowed though, as it modifies certain game files. AFAIK, gameplay is unaffected. This utility also fixes problems with multiple cores and hyperthreading. (not sure about this one currently) - The Steam and GOG releases of the game come with ddfix.
• There is also a utility that lets you play Dark Engine games (like Thief) in widescreen. Again, I'm not sure if it will be allowed as it modifies certain game files and also isn't mandatory for recording. You can get it here. If you use it in combination with ddfix, be sure to install ddfix first. (probably not allowed at all, affects gameplay in a sense) - ddfix allows custom resolutions
• Fogging may look ugly on newer graphic cards, fortunately it can be turned off. If it looks good, you still want to turn it off on Life of the Party because it's broken in that mission.
• When hardware acceleration for audio is enabled, only the ambient sound is captured. Turn it off while recording.
