Sony’s December free games for PlayStation Plus Essential include Mass Effect: Legendary Edition. Subscribers can play remastered versions of the classic trilogy at no extra charge. The collection, released in May 2021, includes Mass Effect, Mass Effect 2 and Mass Effect 3 with modernized 4K graphics and tighter gameplay.

Developer BioWare saved the biggest upgrades for the 15-year-old original. While the non-remastered version is nearly unplayable by modern standards, the remaster is friendlier for modern gamers with more consistent weapon accuracy, tighter camera controls, a dedicated melee button and snappier combat. BioWare also tweaked its handling of the trilogy’s endings, ditching the original approach that required a separate app download to get the best finale. In the new version, your final outcome is based exclusively on your decisions across all three titles.

Other free PS Plus Essential games for December include third-person platform fighter Divine Knockout: Founder’s Edition and open-world RPG Biomutant. In addition to new free games added each month (yours to keep as long as you remain subscribed), PlayStation Plus Essential gives you access to online matchmaking in paid titles. The service costs $9.99 per month or $59.99 per year. It replaced the standard PS Plus earlier this year, when Sony added more expensive Extra and Premium tiers to compete with Xbox Game Pass.
