37. Mad Science

Keep clearing the next few rooms until you can blow a hole on the floor in order to catch up with Salem. In the lower floor, avoid using guns as one stray bullet is enough to make the barrels explode and cause a chain reaction.

The enemies here are just machete-wielding thugs so engage them in hand-to-hand combat and kill them with ease. Continue through the rooms until you find a big vent to push. Push it out of the way and continue forth, killing all targets along the way until you reach the end of the section.
