“The battle against fear takes a darker turn in Chapter Three of Light and Rain: Raging Night. Plunging players into the heart of despair as sorrow, death, and corruption threaten to consume the living planet Mogo. Lyssa Drak has unleashed Nekron and the Black Lanterns, using Luzia Cavalera’s transformation into a Gray Lantern to spread sorrow energy that drains and weakens Lanterns. With sorrow spreading unchecked, you must stand alongside Kyle Rayner to save as many as possible before it’s too late.”
What this all means in terms of content additions is a new open world map in the form of Mournful Mogo complete with new story missions, a new Book of the Black raid that comes in various difficulties, a new solo instance in the form of Nekron’s Lair, and lots of new rewards like augments, catalysts, and gear inspired by characters Kyle Reynar and Nekron.
On top of all of the new story content to nibble on, DCUO players are also seeing a couple of flashback instances make a temporary comeback and a Raging Night event that grants unique rewards, one of which being a henchman uplink device that lets players summon a tanking-focused zombie horde.
