Primewood Genesis is the headline feature of the new PUBG Mobile 4.2 update, turning familiar battleground routes into risk-reward zones packed with corrupted plants, new objectives, and ways to rotate and fight. The results are a mode that rewards planning just as much as great aim.

This guide explains what Primewood Genesis is, what changed on the map, how Primewood Purification works, and how to use key mechanics such as the Prime Eye, Sacred Buds, and Sacred Fruit.

What Is Primewood Genesis In PUBG Mobile 4.2?

Primewood Genesis is the themed gameplay for PUBG Mobile Version 4.2, built around the “Primewood” awakening and corruption spreading across the battlegrounds.

The update arrived on January 7, 2026, without interrupting service. Primewood Genesis is available for a limited time and is scheduled to end around March 10, 2026.

PUBG Mobile 4.2 Primewood Genesis Map Changes

The most significant map changes in Primewood Genesis are the distribution of loot routes and early combat encounters.

On Erangel, five urban zones have been redesigned: Hospital, Pochinki, Sosnovka Military Base, Yasnaya Polyana, and Mylta. In particular, corrupted plants will now appear in urban spaces, and taking them down can open crates, turning PvE interactions into fast looting.

Then there’s the Corrupting Swamp, a high-risk objective area tied to corrupted flowers and the Corrupting Mega Flower encounter.

PUBG Mobile 4.2 Primewood Purification Event Explained

PUBG Mobile 4.2 Primewood Genesis isn’t just match-to-match chaos. It also includes Primewood Purification, a server-wide themed event where players collectively push progress.

How Primewood Purification Works

Any of the following actions add to the server’s overall Primewood Purification progress:

• Clear Corruption Flowers in the Arborum Sanctuary
• Defeat the Corrupting Mega Flower in the Corrupting Swamp
• Plant Sacred Buds and grow Sacred Fruit

Purification Rewards

As the server purification hits key milestones, new tools can be added to matches:

• 50% purification progress: Bramblewood Scorpion becomes available in matches, adding new rotation and fight options.
• 100% purification progress: Targeting Vines becomes available in matches. It’s a swing item that can enable both aggressive plays and defensive resets.

PUBG Mobile 4.2 Prime Eye: How To Use

The Prime Eye is one of the most unique mechanics in Primewood Genesis because it turns information and positioning into a “special ability” moment. It starts at the Ishtar Gate, where you compete with other players for the Prime Eye artifact.

After acquiring it, the Prime Eye grants a bird’s-eye view that can influence the match through map control tools.

Prime Eye Tips

• Use it when the squad is stabilized, as the Prime Eye’s value drops when everyone is scrambling.
• Scout rotations and likely choke points, then decide whether to reposition.
• Don’t overstay the moment. Get the info, use the skill, and return to normal gameplay.

PUBG Mobile 4.2 Sacred Buds and Sacred Fruits

Sacred Buds/Sacred Fruits are designed for cross-match planning, letting players plant in one match and potentially benefit later. This is the Primewood Genesis mechanic that quietly rewards players who think ahead. 

After playing a couple of matches on the map, the Sacred Bud will gather enough energy to turn into Sacred Fruit. You can interact with it to claim supply rewards. The fruit has different tiers, with Gold Fruits being the strongest ones, as they can spawn the treant ally Barkle to fight alongside you.

How To Use Sacred Buds and Sacred Fruits

• Plan the fruits in a safe zone, not in the middle of a hot POI.
• When going back to harvest your Sacred Fruits, approach them carefully, as other players might have set traps.
• If the fruit is being contested, you’re often better off holding cover and letting the other team expose itself first.

PUBG Mobile 4.2 Smart Partner: Barkle, The Treant Ally

After the Penguin ally in the PUBG Mobile 4.1 update, Primewood Genesis adds Barkle, a Treant smart ally built for support play. Barkle appears on Erangel and Livik, and you can invite him to the team, then give orders through voice chat or the command wheel once he becomes an ally.

Barkle Skill Summary

These are Barkle’s core commands:

• Combat: Pushes forward and attacks while the recruiter is fighting.
• Defend: Returns to the recruiter and blocks shots.
• Rescue: If you’re knocked, Barkle carries you to safety and uses his own HP to save you.
• Carry: Can be used as a transport to a chosen location on command.
• Heal: If Barkle is defeated while you’re around, he can restore HP and Energy.
• Supply Detector: Barkle helps you find nearby supplies.
