Game description from the publisher:
Sudden Death, a bone-breaking, pulse-pounding expansion for Blood Bowl: Team Manager - The Card Game, brings a host of options to the pitch, including three new teams, new Contract payouts, new enchanted balls, and more.
The Dark Sorcery Syndicate union features dabblers in forbidden magics who just don't know when to stay down. The undead Champions of Death tear up the pitch – sometimes literally as they raise new zombies and skeletons from the corpses of former Blood Bowl players. The vampires of the Black Fangs are always thirsty for victory (and blood). And the Dark Elves of the Naggaroth Nightmares are happy to give both teams plenty of fresh corpses with which to play.
