Tomb Raider I-III Remastered Starring Lara Croft

Around halfway through the "Furnace of the Gods" level, you will come across a molten gold river, where you'll have to jump across by following some blocks. At the end of the section, you will be able to climb to a corridor (it is just after finding the second secret, you will also be attacked by crows at this point).

Save before entering this corridor, where there is a rolling disc waiting for you. You will have to run through this corridor, taking refuge in the alcoves on the sides, without stopping and without taking any damage whatsoever.

It's not hard but you'll probably have to try more than once. Be careful to not stop when you reach an alcove, then get behind the blade and continue until the end. The corridor is not long at all so it shouldn't be too hard.
