by Greg Martin

Sony Interactive Entertainment has announced the PlayStation Plus Monthly Games lineup for December, adding five titles to the service for members beginning December 2. The selection includes LEGO Horizon Adventures, Killing Floor 3, The Outlast Trials, Synduality Echo of Ada, and Neon White. All titles will be available to claim until January 5.

LEGO Horizon Adventures, released earlier this year, adapts Guerrilla Games’ Horizon franchise into a family-oriented action-adventure format. Players assume the role of Aloy and can play either solo or in cooperative modes.

Killing Floor 3 joins the lineup as the latest entry in Tripwire Interactive’s cooperative first-person shooter franchise. The title continues the series structure of wave-based combat against engineered creatures created by the in-universe conglomerate Horzine.

The Outlast Trials will be available to PlayStation Plus members on both PlayStation 4 and PlayStation 5. Developed by Red Barrels, the game places players inside a series of psychological trials conducted by the fictional Murkoff Corporation. As with earlier entries in the franchise, the title focuses on evasion and survival rather than combat.

Synduality Echo of Ada, set in a post-apocalyptic world in the year 2222, incorporates resource collection and mecha-based traversal. Players explore hazardous environments while managing threats from mutated creatures called Enders.

Rounding out the lineup is Neon White, a first-person action game that combines movement-based platforming with card-driven mechanics. Players complete time-based stages while eliminating targets, with replayability centered on optimization and leaderboard performance.

Sony also reminded subscribers that November’s titles Stray, EA Sports WRC 24, and Totally Accurate Battle Simulator remain available to claim until December 1.
