I imagine this is all Joker has been doing since they got back from the Omega 4 Relay. It'd probably get annoying if it weren't so damn cool.
All I did was just extract the models from Mass Effect 2's PC assets, bring them into 3ds Max, throw their textures on them, and then I moved them around to pose them.
Then I modeled some aviators because that BAMF needs some aviators.
(The models and all of their assets belong to BioWare.)
