Harry Potter: Death Eaters Rising captures the difficulties and terrors Harry Potter, Ron Weasley and Hermione Granger face during their fifth year at Hogwarts as they scramble to persuade the wizarding world of Voldemort's return.

In Harry Potter: Death Eaters Rising, each player must assemble teams of witches and wizards from the Order of the Phoenix, Dumbledore's Army, and Hogwarts to fight against the growing threat of the Dark Lord. Starting with either Harry Potter or Hermione Granger representing Dumbledore's Army, Minerva McGonagall or Albus Dumbledore from Hogwarts, or Nymphadora Tonks or Sirius Black from the Order of the Phoenix, players will be able to rally a variety of year-5 characters to their cause, such as Ginny Weasley, Luna Lovegood, Alastor Moody, Mrs. Norris, Severus Snape, and Rubeus Hagrid. The collective armies and players must then work together to stop the spread of dark influence throughout the wizarding world.

Players have to battle Dark Wizards Peter Pettigrew, Bellatrix Lestrange, Lucius Malfoy, and others who bear the dark mark for control of key wizarding world locations, including the Ministry of Magic, Diagon Alley, and Hogsmeade Village. To be successful, players must vanquish Voldemort's Death Eaters and eventually defeat You-Know-Who before they corrupt and take control the wizarding world.
