I am wondering if are there any benefits in making headshots in Orcs Must Die!? I mean except the fact that you can take down an orc faster.
There's no real benefit of headshots game play-wise, other than killing the enemies faster.
However, if you're looking to get a decent high score racked up, the headshots can be usable in a few ways:
Note: Both of these points can be done without headshots, thus making it a lot harder. However, it does also require a lot of skill, to hit the headshots at the exact time you need to.
