Combine tape and any kind of bottle.

I got this on Episode 3. At the beginning of the "Stiches and Truth" part you will find yourself at the top of the ladder and back in the park. There are 3 Humanz ahead of you. Equip a flammable bottle and your gun. You'll have to hold down (L1) and walk around trying to lure the 3 close together. When you think you've got it, press (R1). You will then enter slow motion and simply use (R1) again to shoot the bottle when it's close to all 3. It may take a few attempts to get the grouping right.

Equip some form of spray and your lighter. Press (Triangle) to go into first person and then press (R1) to spray flames toward an enemy.

Combine a hankerchief or bandage with any flammable bottle.

Toward the end of the "Down the fissure" segment of Episode 3 you will see a circular room filled with water. There is a ladder on the opposite side that is blocked by a cocoon. You can throw and shoot a flammable bottle or use your lighter with a spray to burn it.

Equip a flammable liquid bottle and your gun. Hold (L1) and press (R1) to throw the bottle and you will enter slow motion. Press (R1) again to shoot it.

Combine a flammable bottle with some tape.

Combine your gun with a flammable liquid/bottle.

Combine a flammable bottle with some tape. Then combine that with a glowstick.

Combine an empty bottle with some tape. Add a bandage or hankerchief and then add in an emergency flare.

I did this in Episode 3. I used some debris and knocked down a Humanz. Sometimes they will jump up quick so knock them down again. At some point they are likely to stay down for some time. Combine a flammable liquid with you gun and enter first person mode. You should see red lines on the enemies. When I got it the red lines on the leg were rather thick so it made it easy to shoot. Shoot a line (fissure) and you'll get the trophy.

Combine a flammable bottle and some tape. Then combine it with a full box of ammunition.

I did this in Episode 3. When in the building with the 3 evil roots, a fissure will attack you when you take the elevator up. You can burn the fissure in any manner you want.

You'll get this by playing Episode 5. To beat it, equip a flammable bottle and your gun. Hide behind a column and wait for it to stop throwing blades at you. Peek around and throw the bottle, shooting it when it's close to it. It will do a new attack soon so hide behind a column when the area behind it glows. He will attack the column at which point you should run to another. Repeat this process 3 more times to get the trophy. There are additional flammable bottles near some of the corners.

First spot to do this is in the lobby in Episode 2. The Ratz are gray mutated creatures. There will be 3 in the lobby. Run up to them and press (R2) to kick them. They can't die this way so repeat until you have the trophy. They can be found elsewhere in the game so you can get it later too.

During the "Filthy Waters" segment of Episode 3 you'll come across a room with a grated walkway over electrified water. Across the room will be a small mass that throws out Ratz. Shoot this with a fire bullet or get close and spray it with your ligher. There are other locations for these as well so just keep an eye out.

These are the flying bat like creatures. At any point you can use a spray with your lighter to catch one on fire. Many of these are present during Episode 4.

Toward the end of the "Down the fissure" segment of Episode 3 you will see a circular room filled with water. This is the same room with the cocoon. Look in the water and you'll see a goldfish swimming around. Shoot it.

Once you have the PDA (Episode 3), open it up with (Select). Go to Contacts and then call each of the 4. Once the last call is made you'll get the trophy.

I got this in Episode 7 or 8. I don't think there are any cars without keys prior to that. Enter a car and the start up will be blocked out. Look toward the ignition and press (X) when the hotwire symbol appears. Press (LS) and (RS) toward each other. If nothing happens, press both sticks up to try the next wires. Do this until a meter appears with a line moving left to right. Press (R2) in the green section toward the right and the car will start.

You'll get this in Episode 2. You'll need to break the window of the car and enter it.

I got this near the end of Episode 3. You need a knife or a screwdriver and an empty bottle. Equip both and go up to a gas tank on a car and hit (X). The gasoline will start to leak and then press (X) again. The longer you sit there the more you get, however to get the trophy just do those steps.

When you enter a car, look up and hit (X) when prompted. You'll get this in Episode 2 by default.

You can sit and drive during Episode 2 over and over if you want or drive around in the park during Episode 3/4. However by just playing the game I unlocked this during a segment in Episode 4. I'd advise just to play and you'll get it.

If you get hurt severely, a timer will appear in the lower left of the screen. If the timer reaches 0, you die. When it appears, hit (Left) or (Right) on the d-pad. If you have bandages in your inventory, press (R1) to bandage the severe wound. You may or may not get this just playing through the game.
I chose to do this in the kitchen area of Episode 5. It is the part where you have to throw a molotov over the broken wall to burn a bunch of ratz nests. You can shoot the dead guy on the floor once to get the ratz to stay off of you if you want. Anyway, there are tons of bottles in the kitchen, so I made a molotov and threw it on the floor. Just stand on it and get hurt. You'll get the countdown each time. After each explosion, just use the bandage. Repeat until you get the trophy.

I don't think you have to burn half the number of the roots of evil. I burned less than half but my gauge filled to 50/100 and the trophy popped. Anyway, see Blazing Roots for more information.

This one can have a mind of it's own so you may need patience for this trophy. You can find plenty of supplies around Central Park, you'll just have to explore. Check larger buildings for plenty of supplies typically. I made this list after researching a bit online and also after getting the trophy myself.

*Transfer liquid from one bottle to another

*This was the one that kept me from getting the trophy. I transferred some flammable liquid from a plastic bottle that had (8) in it to a glass bottle that had (8) in it. I simply filled the glass bottle to the max (10) and the trophy popped.

Complete all 8 episodes in the game.

Roots of evil are only available to burn during Episodes 3 (3), 4 (4), 7 (8) and 8 (18). The number in parenthesis are the number of roots available in that episode. Press select and then (X) on the world icon. This brings up your map and the roots are shown by small static circles on the map. Explore a bit in the circle and you should find the root(s).

If you need help, here is a link with all the locations and how to get to them: Alone in the Dark - PC PS2 PS3 XB360 WII/Roots - WikiCheats

I got this during Episode 8 while going around burning the rest of the roots of evil. If you don't somehow get this by playing normally, run around Central Park in episode 8 killing Humanz and you'll have it in no time.
