"A bland sad protagonist with all the charisma of a rock with a frowny face, a mystery box-style narrative that only ends with more mystery boxes, a combat system that wants to be multiple entirely different games. The Callisto Protocol might function, and it’ll certainly have its launch issues patched out in due time, but in no way can I recommend it to anyone but the most morbidly curious. Everything was stacked in this game’s favor, and it still wasn’t enough. We didn’t need Dead Space 2.0 - we just needed a cohesive, focused game. Instead, it's an oddly soulless concoction of unfocused ambitions, poor planning, and inconceivably amateurish design. Whether you're winning or losing, Callisto Protocol never feels right."

About The Artifact Protocol
The Artifact Protocol is a psychological horror game crafted by Liam Butler and launched on PC on September 5, 2025. It positions players as a silent observer navigating fragmented memories trapped within cursed artifacts. Each of the five levels immerses you in a victim's final hours, forcing you to piece together their stories while evading personalized threats. The game thrives on tension and ambiguity, blending environmental storytelling with surreal visuals. Its indie pedigree shows in the minimalist design but not in scope, every nightmare is a self-contained horror vignette with unique antagonists and themes.
Gameplay
You wander dimly lit spaces, interacting with artifacts to trigger visions. These visions force you into the victim’s perspective, where you must survive encounters with grotesque creatures while uncovering cryptic clues. Mechanics revolve around environmental puzzles, adjusting objects in real time to alter memory sequences or bypass obstacles. Controls are responsive but limited to movement, crouching, and artifact activation, which keeps the focus on atmosphere. Sessions last 10, 30 minutes per nightmare, with sudden shifts in perspective and audio cues creating persistent unease. The lack of combat or dialogue deepens the claustrophobia, demanding close attention to subtle environmental details.
What Players Think
PlayPile users rate it 8.2/10, with a 8.4/10 community score. 68% finish the game, averaging 4.5 hours. 72% tag it as "Anxious," 55% "Curious," and 38% "Frustrated." Metacritic aggregates 78, praising its "haunting atmosphere" but noting "uneven pacing." One review highlights the "relentless dread," while another calls it "overly cryptic." Achievements (50 total) include unlocking bonus lore, with 850G required for platinum. The frustration stems from obtuse puzzles and short runtime, though 83% of completers rate it "Worth the price."
PlayPile's Take
The Artifact Protocol works best for fans of cerebral horror and brief but intense experiences. At $24.99, it’s a risky but rewarding purchase for those who appreciate slow-burn dread over action. The 50 achievements add replay value, but 38% of players abandon it due to confusion. If you thrive in ambiguity and value mood over mechanics, this is a quick, unsettling diversion. Pass if you prefer clear narratives or extended gameplay.
