Orcs Must Die! Unchained

At first the game will be Vert- but you can easily change that via config edit!
Find the "SpitfireEngine.ini" in "\Documents\My Games\Orcs Must Die Unchained\SpitfireGame\Config" and search for the code
AspectRatioAxisConstraint=AspectRatio_MaintainXFOV
Simply change the X to Y axis and you're done!
At least with the FoV... HUD is fixed on the outer boarders, mouse pointer is HUGE and so are the enemie mob health bars.
