Mhm, that is definitely Grunt eating a sandwich. Just look at him go.
I got bored and decided to do this because my brain thought it would be cute.
So...here it is.
All I did was just extract the models from Mass Effect's PC assets, bring them into 3ds Max, throw their textures on them, and then I moved them around to pose them.
(The models and all of their assets belong to BioWare.)
