Legal representatives for Fallout 3 publisher Bethesda Softworks have sent a cease and desist letter to Xreal, an indie studio currently working on “Fortress Fallout”, demanding the developer change the game’s title and no longer applies for its trademark.

At the heart of Bethesda’s complaint is the use of the word “Fallout” in Xreal’s title. It is not clear if anything else ties the two games together: Fortress Fallout is a 2D, single-screen, iOS tower defence game set in a grassy mountainside location, while Fallout 3 is a sprawling 3D action-RPG-shooter set in a post-apocalyptic USA.

Xreal founder Howard Marks, having been advised by legal counsel, said changing the name is the best decision for his team. Marks described Bethesda as a “litigious” corporation, adding that it was difficult to challenge the claim due to Bethesda’s vast resources.

“It’s pretty silly. Congratulations Bethesda. You won. You beat us. You showed us who’s boss,” he said in the video above.

Marks is now asking the YouTube community to nominate a new name for the game, with numerous users suggesting that “Fortress Outfall” would be an ideal alternative.

Trademark legal disputes are not uncommon at Bethesda. In August 2011, the corporation sent a cease and desist letter to Minecraft developer Mojang, asking it to stop developing a project under the name “Scrolls”. Bethesda’s legal team argued that it owned the rights to “The Elder Scrolls” name, and that Mojang’s project was clashing with that trademark. The two companies settled out of court.

Bethesda is also in a legal row with the company behind Oculus Rift.

Bethesda is heading to E3 in June to deliver the publisher’s first ever press conference. Among the list of rumoured games to be announced at the show are Fallout 4, Dishonored 2 and DOOM, though the publisher has yet to announce its line-up.

Halo: Nightfall, the episodic live-action TV series set between the events of Halo 4 and 5, will be released as a collection across North America and Europe in March.

The five-episode season, produced by Ridley Scott and directed by Sergio Mimica-Gezzan, originally aired on Xbox 360 and Xbox One between November and December. Now the series will come to DVD and Blu-ray from March 17, with all episodes merged together into a feature-length film.

Microsoft has issued a new trailer ahead of the film's release, adding that Nightfall will also be available on “digital channels”.

Halo: Nightfall tells the story of Jameson Locke who, according to the show’s official blurb, is “a legendary manhunter and agent with the Office of Naval Intelligence (ONI), Earth’s most powerful and secretive military branch.”

Fans who have watched the show already will have witnessed how Locke transitions the narrative between Halo 4 and 5, and how he will play a key role in the next installment.
