Transfered from the Original Forums, achievement guide for Tomb RAIDing in “The Dusty Dark”.
This one has to be done in one go (the count resets if you leave), and cannot be done at the same time as Flawless Archaeology.
Starsmith's General Guide
By the time you reach the first puzzle, you should have 5. One set on fire with the torch nearish the side mission.
Before you reach the Leap of Faith pit, you should have 20 in your count. One by the Eye of Horus and one by the bust of Akhenaten need to be set on fire.
You’ll need to fall in the pit; there are some to fight down there, plus one in the northwest corner that needs to be set on fire. Watch on your trip back up for another that needs to be set on fire. This will bring you to 26.
Before you reach the boulder, you should have 36; one near a torch in a rubbly corner needs to be torched.
Before you reach the acid trap, you should have 41. Don’t use the button to set the chasing mummies on fire–you need to torch a scarab in the room with the lore, fight a couple more in there, and torch one just outside one of the doors that will close when you hit the button.
By the time you get to the jump puzzle room, you should have 74. Be sure to look around the room itself for another, which will be 75. There’s a torchable bug in a corner the slopes downward, somewhere before you reach the puzzle room.
Before you reach the room with the diamond shaped puzzle, you should have 92 scarabs. Number 93 is in the room itself. In the maze before you get to this room, there are two torchable scarabs.
Before you reach the gauntlet of six mummies, you should have 98 scarabs. One you can set on fire is near a bust of Nefertiti, and another is nearish a dead end with some webs and rubble.
To get the last two, run through the mummy gauntlet, jump down and hit the button that kills them, then jump back up to find a torchable bug. Go back into the labyrinth room and look around the far edges for the last one!
Prosper01's Step by Step
There are 3 kinds of scarabs.
Hostile scarabs will attack on sight. They must be killed in combat.
Neutral scarabs will not attack on sight. They can be killed by Igniting your torch.
Scripted scarabs will sit still until you approach, then run under rocks or into walls. They can not be killed nor targeted. They will register as dead after they disappear.
Please note that it is impossible to do this achievement at the same time as Flawless Archaeology .
I apologize for the probably vague directions, this is a work in progress. If anything is particularly unclear, please let me know.
