Death Troopers were introduced in Joe Schreiber's 2009 novel appropriately titled Star Wars Death Troopers, and Battlefront News! wonders whether they might make an appearance in the next Battlefront.
The book follows an Imperial prison ship known as the Purge, which is home to 500 of the galaxy's most ruthless killers. Eventually the Purge breaks down in an uninhabited part of the galaxy, and the only hope for those onboard is a seeminly abandoned Star Destroyer found floating in space.
When a boarding party sent to search for supplies returns, only half of them have made it and the rest bring with them a terrifying disease which threatens to wipe out everyone on board within hours.
However, Disney has made most of the extended universe non-canon and it may not be possible for DICE to include them. Battlefield News! suggests that maybe DICE could still work around this, and add a Call of Duty zombies-like mode for the game.
It was recently confirmed that Star Wars Battlefront will launch in late 2015.
