STALKER 2 Side Quest: Delving into Scientific Anomalies

In Stalker 2: Heart of Chornobyl, players exploring The Zone will encounter numerous NPCs, often leading to quests ranging from minor tasks to substantial side missions like "For Science!". This mission involves Skif meeting Yaryk Mongoose, who'll then request activation of a second measuring device atop a silo. While short, 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 by locating Yaryk Mongoose in the Central Elevator area within the Chemical Plant. Upon approaching, Mongoose will contact Skif via radio, requesting a meeting at the building.

Enter the Central Elevator, proceed left past the conveyor belts, and ascend the rusted stairs. Mongoose is on the first floor; vault the railing to reach and speak with him. He'll explain the need to activate a second device on a nearby silo, initiating the mission once you agree.

Reaching the Silo's Summit

Exit the room and climb to the building's roof. Eliminate any rodents encountered. A room with broken windows provides access to an exterior walkway and ladder leading to the silos.

Jump to the connecting walkway, equipping your bolt-action weapon to counter electro anomalies. Proceed left along the silo's top to locate and activate the second measuring device.

Activating the device will attract a pack of Bloodsuckers. Choose to eliminate them or evade them to reach Mongoose.

Confronting Yaryk Mongoose

Upon reaching Mongoose, he'll explain the experiment's unintended consequences. Players can choose to kill Mongoose for endangering Skif or accept the reward and depart. Neither choice impacts the game significantly. Killing Mongoose allows looting the Malachite pass from his corpse.

However, choosing the non-hostile option is recommended, yielding both the Malachite Pass and additional coupons. The pass grants access to the STC Malachite base, unless already accessible via main missions.
