The first real single player DLC Harley Revenge along with the GOTY version of Arkham City was officially announced today, (we posted rumors about the DLC months ago). However, you don’t have to buy the GOTY to get the Harley Quinn DLC. It’ll be sold by itself on May 29th PSN and May30th Xbox (other sites reporting April are misinformed, Sarah Riikku, Rocksteady PR, updated via twitter about the April mistake). Here’s the Press release for the DLC:
The Harley Quinn’s Revenge mission sends players back into Arkham City to face their final challenge as they interchange between playing as both Batman and Robin. Gamers must utilize each of the characters’ unique combat and investigative skills to uncover Harley’s vengeful plan and shut the gates on the urban mega-prison forever. In addition to experiencing a new storyline, fans can explore new environments and face-off against Harley’s all new gang of thugs.
GOTY Edition has of all five of the sequel’s downloadable content packs. These include character DLC (Catwoman, Nightwing and Robin), challenge maps, as well as the Arkham City skins add-on. The North American version of the bundle will also have a download code for the animated movie Batman: Year One. It comes out May 29th.
The trailer mostly shows the GOTY edition but you get a short glimpse at the dlc toward the end.
