So I like Nuska's Oblivion Character Overhaul version 2. But I also like Room207's Orsimer Overhaul.
Only one way to solve this dilemma; MERGE THEM TOGETHER! :D

This is a little patch that replaces the orc head meshes in Oblivion Character Overhaul version 2. The male orc mesh is replaced with Room207's Orsimer Overhaul, while the skull and brow of the female orc mesh has been edited to match. The hair meshes are also replaced with the ones from Room207's Orsimer Overhaul.

Updates:
- 14th February 2014: Just some minor rebranding. My Tumblr username is TheNathanParable, and I want the "Author" name and filenames to match.
- 8th January 2014: Added optional "Nuska Style" male head.
- 31st December 2013: Original upload.

Requirements:
Nuska's Oblivion Character Overhaul version 2. That's it really. As long as you've got that installed and working you shouldn't have any issue.

Installation:
Simply install it after Oblivion Character Overhaul version 2 (and preferably after any body replacers you're using), either manually or with a modding tool (such as NMM or Mod Organizer).

Optional Nuska Male Head:
This is for those who like the rounded skulls and hair compatibility that Orsimer Overhaul brings, but prefer the way that Nuska's male orcs look face-wise. This includes a version of Nuska's male orc mesh that has been edited to have the same rounded skull as Orsimer Overhaul. Simply install it over the main file (OCOv2 Orsimer Overhaul).

Credits:
Nuska - for her brilliant Oblivion Character Overhaul version 2, and for pushing me in the right direction when it came to editing her head mesh.
Room207 - for his equally brilliant Orsimer Overhaul.
Bethesda - for the vanilla teeth and mouth meshes used by the male orcs.
