Alone In The Dark

I recommend waiting to do this achievement until Episode 7. By that point, you'll basically have free run of the entire park and be able to move around to find the components that you need.

Here are all the combinations.

Explosive Plastic Bottle + Double Sided Tape + Handkerchief + Flare
Explosive Plastic Bottle + Double Sided Tape + Handkerchief + Glowstick
Explosive Plastic Bottle + Double Sided Tape + Handkerchief + Bullets

Explosive Plastic Bottle + Double Sided Tape + Bandages + Flare
Explosive Plastic Bottle + Double Sided Tape + Bandages + Glowstick
Explosive Plastic Bottle + Double Sided Tape + Bandages + Bullets

Explosive Glass Bottle + Double Sided Tape + Handkerchief + Flare
Explosive Glass Bottle + Double Sided Tape + Handkerchief + Glowstick
Explosive Glass Bottle + Double Sided Tape + Handkerchief + Bullets

Spray Bottle + Double Sided Tape + Flare
Spray Bottle + Double Sided Tape + Glowstick
Spray Bottle + Double Sided Tape + Bullets

Explosive Glass Bottle + Double Sided Tape + Bandages + Flare
Explosive Glass Bottle + Double Sided Tape + Bandages + Glowstick
Explosive Glass Bottle + Double Sided Tape + Bandages + Bullets

Bloodpack + Double Sided Tape

Glowstick + Double Sided Tape

Flare + Double Sided Tape

Combine two bottles of liquid together.

By Episode 7, you'll have a pretty good idea of where to find different things, but three reliable locations are the pump room near the lake in the middle of the map where you encounter the goo in the basement, the large two-story house where you find your first Root of Evil in Episode 4, and the courtyard near the obelisk in the northeast corner of the park. The last location is especially useful for finding blood packets.
