BioWare tenure
Mac Walters joined BioWare in September 2003 as a writer on Jade Empire, where he contributed to quests, dialogues, and character arcs, helping shape the game's martial arts RPG narrative set in a mythical Chinese-inspired world.[7] His work laid foundational experience in interactive storytelling, emphasizing player choice and companion relationships that would become hallmarks of BioWare's style.[3] Walters advanced to senior writer on the original Mass Effect in 2007, co-developing Commander Shepard's story arc and companion narratives, including romance options and loyalty missions that integrated player decisions across the galaxy-spanning plot.[7] Promoted to lead writer for Mass Effect 2 in 2010 and Mass Effect 3 in 2012, he oversaw a team of approximately eight writers, guiding major plot decisions such as the Reaper invasion's escalation and resolutions to arcs like the quarian-geth conflict and the genophage cure.[8] The Mass Effect 3 ending drew significant controversy for its perceived ambiguity and lack of closure on player choices, prompting widespread fan backlash and a free extended cut DLC; Walters defended the narrative's thematic focus on sacrifice and legacy while acknowledging the need for clearer epilogues.[7] As creative director for Mass Effect: Andromeda in 2017, Walters oversaw narrative design for the spin-off, pivoting from procedural generation to handcrafted stories amid development challenges with the Frostbite engine and a newer BioWare Montreal team, though the game received mixed reviews for its exploratory tone and facial animations.[7] He co-authored the tie-in novel Mass Effect: Initiation with N.K. Jemisin, expanding on Lieutenant Cora Harper's backstory and bridging to the game's Andromeda Initiative lore.[9] Transitioning to narrative director on Anthem in 2019, Walters integrated story elements into the live-service looter-shooter, focusing on faction dynamics and environmental lore despite the project's struggles with scope and reception.[7] In 2021, Walters served as project director for Mass Effect Legendary Edition, coordinating the remaster of the trilogy with updated visuals, gameplay tweaks, and quality-of-life improvements that revitalized the series for new players.[2] By 2022, he took on production director duties for Dragon Age: Dreadwolf (later retitled Dragon Age: The Veilguard), managing production challenges including team restructuring and scope adjustments during BioWare's post-Anthem recovery, contributing to the RPG's evolving narrative before departing in early 2023.[3] Throughout his two-decade tenure, Walters significantly influenced BioWare's narrative-driven RPGs, advancing player agency, diverse character development, and epic sci-fi/fantasy worlds during the studio's peak creative output.[10]Departure from BioWare
In January 2023, Mac Walters announced his departure from BioWare after nearly two decades with the studio, having made the decision at the end of 2022.[11][12] In a LinkedIn post, he described the 19 years as a "life-changing experience" that made the choice "very difficult," highlighting his work with talented teams on projects including Jade Empire, the Mass Effect trilogy, Anthem, and as production director on Dragon Age: Dreadwolf.[11][12] The announcement, first spotted by Eurogamer and reported across outlets, came amid BioWare's ongoing transitions under Electronic Arts (EA) ownership, which included project pivots such as the cancellation of Anthem in 2021 and a renewed focus on single-player titles like Dragon Age: Dreadwolf following multiple development restarts.[11][12] Walters cited several personal and professional motivations for his exit, including a desire to pursue new creative challenges after the success of Mass Effect: Legendary Edition in 2021, which he viewed as a fitting "bow" on his contributions to the franchise and led him to conclude, "I don’t want to do any more Mass Effect after this."[2] He expressed burnout from his long tenure, noting in a December 2023 MinnMax interview that after 19 years, he felt ready for a change and sought opportunities for original projects, but inquiries within BioWare and EA revealed no such paths "for the foreseeable future" due to the company's emphasis on established intellectual properties.[2] This aligned with broader industry pressures at BioWare, where EA's strategic shifts toward more "agile" development—foreshadowing 2023 layoffs of about 50 roles—limited innovation on new IPs amid focuses like Dragon Age: Dreadwolf.[13] In subsequent interviews with IGN and PC Gamer in 2023, Walters reflected on his legacy at BioWare, expressing pride in Mass Effect's enduring impact on storytelling in games and its role in advancing narrative depth in RPGs.[14][2] He also addressed lessons from controversies, such as the backlash to Mass Effect 3's ending in 2012, acknowledging the importance of community feedback in shaping future narrative resolutions and how it informed his approach to player agency throughout his career.[14][2] During his transition, Walters completed remaining obligations on ongoing BioWare projects, including contributions to Dragon Age: Dreadwolf, before fully exiting to take a career break for personal pursuits.[12][11] This period allowed him to recharge after his extensive tenure, setting the stage for independent endeavors.[2]Worlds Untold
Founding and vision
Mac Walters founded Worlds Untold in 2023 as CEO and studio head, establishing the studio in Vancouver, Canada, as a fully remote operation immediately following his departure from BioWare after nearly two decades there.[15][16] The studio's launch was announced on November 16, 2023, in partnership with NetEase Games, which provided funding and operational support to enable the development of original intellectual properties.[15][5] The vision for Worlds Untold centers on creating narrative-driven AAA action-adventure games set in near-future worlds, emphasizing immersive storytelling, mystery, exploration, and player agency to deliver experiences that blur the boundaries between gaming and cinematic media.[15][16] Drawing from Walters' extensive BioWare tenure on titles like the Mass Effect series, the studio aims to innovate by building fresh IPs with "endless possibilities for storytelling" across multiple games and media formats, while avoiding overly restrictive creative constraints to foster diverse, player-led adventures.[16][5] Walters has articulated this as a commitment to crafting "worlds we dream of discovering," filled with wonder, believable characters, and environments compelling enough to linger in players' imaginations.[16] To realize this vision, Worlds Untold initially assembled a core team of industry veterans, including Head of Production Elizabeth Lehtonen (formerly of Dragon Age and The Sims), Head of Art Ramil Sunga (Mass Effect: Andromeda, Dragon Age), Audio Director Sotaro Tojima (Metal Gear Solid, Halo), and Head of Technology Ben Goldstein (Assassin's Creed IV, For Honor).[15] The studio's goals include breaking new ground in global game development by leveraging cutting-edge technology to produce unforgettable, interactive narratives that prioritize depth and immersion over conventional boundaries.[15][16]Projects and operational pause
In November 2023, Worlds Untold announced its debut project, an untitled near-future action-adventure game emphasizing strong narrative elements, mystery, and exploration in a visually stunning world.[15] The studio, backed by NetEase Games, began early development on this AAA title, aiming to blend immersive storytelling with gameplay inspired by Walters' BioWare experience.[17] To support development, Worlds Untold assembled a core team of industry veterans and expanded through targeted hiring in late 2023 and early 2024. Key hires included Sotaro Tojima as audio director (previously on Metal Gear Solid and Halo), Elizabeth Lehtonen as head of production (Dragon Age, The Sims), Ramil Sunga as head of art (Mass Effect: Andromeda, Dragon Age), and Ben Goldstein as head of technology (Assassin's Creed IV: Black Flag, For Honor).[15] Following the operational pause, Lehtonen, Tojima, and Goldstein departed for other opportunities.[18][19][20] The studio, operating remotely from Vancouver, achieved initial milestones such as prototyping narrative systems and world-building concepts during its first year.[21] On November 27, 2024, Worlds Untold announced a pause in operations after NetEase withdrew funding just one year into the partnership, citing a need to align with a new backer better suited to the project's vision.[6] This decision led to the cessation of active development and team activities, with staff encouraged to pursue other opportunities in the interim.[22] In a LinkedIn post, Walters emphasized that the pause was not a closure, stating, "It’s hard to find the right words for this, but I wanted to share that we’ve made the very difficult decision to pause operations at Worlds Untold while we search for a new partner to help bring our vision to life. This isn’t goodbye—there’s more to come, and we look forward to sharing the next chapter with you when the time is right."[6] As of November 2025, no resumption of operations or new funding has been publicly announced for Worlds Untold.[23]Works
