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 short, it rewards players with a Malachite pass, granting access to STC Malachite facilities.
Initiating the "For Science!" Side Quest
The "For Science!" quest begins by finding Yaryk Mongoose in the Central Elevator area of the Chemical Plant. Upon approaching, players will hear Mongoose radio Skif, requesting a meeting.
Inside the Central Elevator, go left past the conveyor belts and ascend the rusted stairs. Mongoose is on the first floor; vault the railing to reach him. He'll explain the need to activate a second device on a silo, requiring simultaneous activation of both. Accepting his request starts the mission.
Reaching the Silo's Peak
Exit the room and climb to the building's roof. Eliminate any rodents encountered. A room with broken windows provides access to an external walkway and ladder leading to the silos.
Jump to the connecting walkway, equipping your bolt to counter electro anomalies. Proceed left along the silo to activate the measuring device. Activating it will attract Bloodsuckers. Players can choose to fight or evade them to reach Mongoose.
Confronting Yaryk Mongoose
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 has significant long-term consequences. Killing Mongoose allows looting the Malachite pass; choosing the peaceful option provides the pass and coupons. The pass grants entry to STC Malachite, unless already accessible through main missions.
