While playing in Conquest Mode as Han Solo, you can occasionally hear one of the Imperial Troopers say, "Hey! Solo shot first! That's not fair!" while Han is killing other troopers. This is a reference to a difference between the Special Edition version of
Star Wars: Episode IV - A New Hope (1977) and the original version. Specifically, the scene where Greedo confronts Han in the Mos Eisley cantina was edited, featuring a laser bolt from Greedo's weapon that barely misses Han's head just before Han kills Greedo. In the original version, Han did indeed shoot first, killing Greedo before Greedo had a chance to shoot (the in-game remark about unfairness presumably referring to the fact that, in the Special Edition movie version, Han clearly killed in self-defense, while the killing of Greedo in the original version was a more questionable use of pre-emptive self-defense).
