Microsoft has continued its Xbox gaming "reset" with layoffs at Halo Studios and the divestment of Undead Labs, the studio behind the State of Decay survival franchise.

The cuts at Halo Studios — Microsoft's internal Halo franchise team, formed from the rebranded 343 Industries — and the divestiture of Undead Labs extend the cost discipline Xbox has pursued across its first-party portfolio through 2025 and into the new year. Both decisions land within the same strategic frame Microsoft Game Studios leadership has telegraphed since the close of its largest acquisition: right-size first-party operations to a publishing model rather than an internal development model.

What Halo Studios' layoffs signal for the franchise

Halo Studios carries the heaviest franchise obligations in the Xbox first-party stable, with Halo Infinite's live service operations and the development of future Halo entries running in parallel. Reducing internal headcount at the studio typically narrows the scope of those efforts, with remaining work absorbed by external partners or further attrition.

Halo has shaped Xbox's consumer brand since 2001, so any studio realignment at the franchise's home studio carries reputational weight well beyond the immediate development cost line. For studios bidding against Halo on Microsoft's first-party slate, the cuts re-open access to subcontract work the in-house team previously absorbed.

Why Undead Labs is being offloaded

Undead Labs, the Seattle-based developer Microsoft acquired in 2018, now returns to the broader market. The studio's lead product, State of Decay 2, has run as a long-tenured live service title since launch, with the team supporting ongoing content updates.

Divestment at this stage of a live service lifecycle typically points to one of two outcomes: a sale to a buyer willing to operate the game independently, or a wind-down that returns the IP to Microsoft. Either path gives Undead Labs access to non-Xbox publishing revenue streams the studio has not had since acquisition.

How the pair fits Xbox's broader posture

Both moves follow a period in which Microsoft's gaming division has integrated major acquisitions, including the $68.7 billion Activision Blizzard deal and the earlier ZeniMax Media purchase. Both transactions materially expanded first-party headcount, and the studio-level reset reflects a deliberate cost realignment.

The pattern — extending cuts to studios built up during the acquisition spree, then offloading peripheral live-service operations — has now reached franchises once considered strategically essential.

What to watch next

The next benchmark sits with any formal Undead Labs transaction: a closing date, purchase price, and buyer name would convert the divestment from a strategic signal into an actionable market data point. For Halo Studios, the post-layoff operating budget and the scope attached to the next Halo entry will determine whether the cuts mark a realignment or a sustained pullback.

The cadence of further studio decisions, plus any internal memo from Xbox leadership on the reset's next phase, will signal whether current cost discipline represents a pause or a steady-state footing for the division.
