The Halloween Event is a suite of gaming tasks and visuals that are reminiscent of the Halloween holiday season. This includes Trick or Treating, costumes, monsters, ghosts, witches, and horror movie cliches such as a Zombie Apocalypse and mad scientist’s monster.
Dr. Kane’s House of Horror

The eccentric scientist Dr. Kane turned his home into a haunted house and has invited all of Paragon City to come and visit. Things are not as they seem in Dr. Kane’s House of Horror, though. Visitors enter the mansion never to be heard from again!
Dr. Kane’s mansion is a zombie-filled nightmare, and while exploring it, you learn of the doctor’s nefarious plot to transform the innocent people of Paragon City into a slavering horde of zombies. As you investigate the halls and rooms of the haunted mansion, you face off against Dr. Kane’s freakish creations, including his greatest handiwork, the giant Abomination.
Dr. Kane’s House of Horrors is a co-op event for four characters of level 15-50. Access this new event through the Team-Up Teleporter (only).
Whispered Rumor Tip Mission

When a character goes Trick or Treating in a Temporary Costume, there is a chance of a Halloween Tip Mission dropping from a ‘Treat’. This Halloween Event Tip will drop even if you already have 3 Alignment Mission Tips. You need to be Level 20+ and not in Praetoria to get this Tip. The Tip is entitled Whispered Rumor and has a jack-o’-lantern picture on it. The Halloween Tip Mission grants some minor rewards plus one of five badges.
Deadly Apocalypse

The Deadly Apocalypse is a type of zone invasion introduced in the Halloween Event of 2009. Haunting Banners representing iconic horrors appear in a zone and are protected by foes that embody that banner’s horror. Players must attack the defenders and then the Banners and then finally a Giant Monster. Rewards include badges and a selection of temporary powers.
Eternal Night

During the event, the entire game is locked in nighttime mode. This is not just a visual effect. All aspects of the game that depend on a day/night cycle are locked to the night side during the event. Enemies that only spawn at night spawn continuously during the event. Banisher, The Slayer, and Haunted badges (Hero side) and Pirate and Spectral badges (Villain side) are examples of badges for which hunting will be much easier during the event.
Note that some zones, such as Cimerora, The Hive and The Abyss are unaffected by Eternal Night.
Zombie Apocalypse

The Zombie Apocalypse is a zone event that uses the Rikti World Invasion engine; random zones throughout the game come under attack by zombies for periods of time as the sky turns red. A new enemy group, Zombies, appear during this event. There are badges for Zombie defeats and an unlockable costume piece, the Pumpkin Head.
Trick or Treat
Trick or Treat

During this event, players are be able to ‘Trick or Treat’ by knocking (that is, ‘clicking’) on mission doors in the various zones. Treats are rewards which include Temporary Powers (a throwable Rock and Costume Powers), Tier 1 inspirations, and Halloween Event Salvage (from defeating the spawned ‘Tricks’) which can be traded in for an extra costume slot. Tricks include spawns of special event enemies for which there are defeat badges.
Giant Monsters

The Giant Monsters from Croatoa, Eochai and Jack in Irons, spawn in most zones (including the City of Villains zones) along with the Unseelie spirits. There are Halloween-specific badges for their defeat (which are different than the badges for the defeat of the regular Croatoan Eochai and Jack Giant Monsters).
