Executive producer Casey Hudson recently tweeted this picture of James Vega. Not much is known about the character except that he is a Human Systems Alliance Soldier and squad member in Mass Effect 3.
While Vega is an experienced soldier, he is unfamiliar with the seedy underbelly and policital workings of the galaxy. According to BioWare , James Vega will reflect the perspective of a new player coming to the franchise. James Vega was originally known as James Sanders, however the name was changed some time after several gaming press outlets visited BioWare and revealed his original name.
