Stalker 2: Exclusive Walkthrough Guide

In Stalker 2: Heart of Chornobyl, players exploring The Zone will encounter various NPCs, triggering quests ranging from minor tasks to substantial side missions like "For Science!". This mission involves Skif meeting Yaryk Mongoose, who needs help activating a second measuring device atop a silo. While brief, completing it rewards players with a Malachite pass, granting access to the STC Malachite facilities.

Initiating the "For Science!" Side Quest

The "For Science!" quest begins at the Central Elevator in the Chemical Plant. Approaching the area triggers a radio call between Mongoose and Skif. Inside the Central Elevator, bypass the conveyor belts, ascend the rusted stairs, and vault the railing to reach Mongoose on the first floor. He'll explain the need to activate a second device on a nearby silo. Accepting his request starts the mission.

Reaching the Silo's Summit

Exit the room and climb to the building's roof. Eliminate any rodents encountered. Access the exterior via a broken window, descend the ladder, and cross the walkway to the silos. Equip your bolt-action weapon to counter electro anomalies. Proceed left along the silo's top to activate the device.

Activating the device attracts Bloodsuckers. Players can choose to fight them or evade them to reach Mongoose.

Confronting Yaryk Mongoose

Upon reaching Mongoose, he'll explain the experiment's unforeseen consequences. Players can choose to kill Mongoose for endangering Skif or accept the reward peacefully. Neither choice significantly impacts the game's progression. Killing Mongoose allows looting the Malachite pass; choosing the peaceful option provides the pass and additional coupons. The pass unlocks access to the STC Malachite base, unless already accessible through main story missions.
