Hunted Demons Forge

Easier to do with E'lara.

The most obvious places was in Chapter 2, there's an "lift" downwards that E'lara rides on. There are archers standing next to an exploding barrel. Shoot it, boom, congrats.

Video showing a good spot for getting the "Kaboom" achievement. The spot is part way into chapter 2 where your partner must help to lower you down a lift.

Note: I've posted this solution because other video is offline.

the best one to do it on is on chapter 2 section 2.3 crane room, not only is the save point 2minutes away but you can gain yourself two more achievements (Is Something Burning?) Kill 20enemies with explosives)15gs and
(Rampage) Kill 20enemies before the platform reachs the ground.)15gs best way i got the Rampage one 3sets of barrels away destroying all of them i just spammed magic at them i got it by mistake
