Once Human: RaidZone is the first high-intensity, no-holds-barred PvP spin-off in Once Human. In this brutal survival jungle, only the echoes of gunfire, hidden traps of enemies, and the constant threat of losing everything remain. From the moment you enter the world, the battle begins. Rely on your combat skills, team coordination, and the power of Deviations to survive in this ruthless land, strengthen yourself step by step, gather resources, and rise to dominance. This is a world made for raiders. Are you ready? Survival Through Raiding — Where Only the Ruthless Survive Step into the RaidZone, where chaos reigns and survival is everything. Every gun, resource, and piece of land must be seized from someone else. Death means losing everything. Want to stay alive? Keep fighting — and never trust too easily. Start from Scratch — Survive with Your Own Hands From bows and axes to tactical gadgets, from long-range rifles and sniper weapons. In the vast selection in RaidZone, customize your unique weapon and armor build to create a tailored combat experience. Utilize the terrain, tactics, and your understanding of combat to engage in exhilarating skirmishes. Build Freely — Shape Your Fortress, Command the Battlefield Establish bases anywhere on the map. Plan your defenses and traps as you see fit. Set traps, raise walls, build your impenetrable stronghold — or a nightmare for your enemies. Your territory is your safe haven and your tactical edge. Defend it. Expand it. Use it to strike back hard. Fair Competitive Environment — No Inheritance, No Overpowering, Pure Skill Everyone starts on equal footing. No external weapons, resources, or blueprints can be brought in. All gear, armor, and Deviations must be discovered and fought for within the scenario. Victory comes from skill, planning, and your ability to adapt—nothing else. Power of Deviations — Turn the Tables with Tactical Abilities Seize rare resources and unlock powerful Deviations to dominate the battlefield. Pyro Dino helps you with firepower and Zeno-Purifier lets you dash forward and cut down your enemies. You can even summon Manibus to precisely destroy target areas.

Verdict

The call

The clearest difference is in-app purchases: PRINCIPLES PROLOGUE at none against Once Human's 27. PRINCIPLES PROLOGUE also leads on review sentiment (76% vs 55%). Once Human's advantage is update cadence (monthly vs every 5 months) and rating (4.5 vs 4.3). On price, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Once Human holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Once Human has 291 ratings behind it against 58, so its average is the more settled of the two. Written reviews complicate that: 76% of PRINCIPLES PROLOGUE's written reviews are positive against 55% of Once Human's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

PRINCIPLES PROLOGUE ships an update every 5 months, Once Human monthly. The most recent releases landed on September 30, 2026 and October 1, 2026 respectively.
