In Star Wars Battlefront hero characters like Luke Skywalker will have to keep killing or vanish from the battlefield. Players become a hero character by finding the right battlefield pickup, but your health constantly decreases over time. As Obi Wan once instructed: "move or die, Luke, like a shark".
These details appeared in a post on the Battlefront site. Senior producer Jamie Keen says that you'll get about two minutes of hero time, possibly five if you go on a serious spree. "In theory, you could play as Luke Skywalker for a whole match, but that is extremely unlikely. That said, the gauntlet is thrown!”"
The post also describes some of Luke's abilities.
"Luke’s movement is varied and powerful, featuring a wide-sweeping, heavy attack with his Lightsaber that can take out large groups of enemies. For more distant targets, the Force Push is a gratifying move that will send Imperial troops flying, and Saber Rush lets you use the Force to propel yourself extremely quickly for a lightning-fast attack."
Hopefully hero characters will be part of the upcoming open beta.
