Fight back the dark forces that have invaded the City. Take on Halloween-themed enemy variants like Pumpkintiles, Haunted Biters and Witch Banshees to obtain Treats. Find Baka the Unfortunate and exchange the candy for the Venom Sting knife, the Nightmare Claw, scary masks, or other weapons and special items. Remember about the Trick-or-Treat effect that will come up when fighting enemies or when eating chocolate bars. It can bestow powers upon you or make your life hell. Watch out when you're out there, for the oncoming nightmares could lead to your downfall.
