In Stalker 2: Heart of Chornobyl, players exploring The Zone will stumble upon various NPCs, sparking a range of quests, from small tasks to substantial side missions like "For Science!". This mission begins with a rendezvous between Skif and 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 the STC Malachite facilities.
Initiating the "For Science!" Side Quest
The "For Science!" quest starts within the Central Elevator area of the Chemical Plant. Approaching this location triggers a radio call between Mongoose and Skif. Mongoose requests Skif's presence.
Upon entering 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 him. He'll explain the need to activate a second device on a nearby silo, initiating the quest once you agree.
Reaching the Silo's Summit
Leave 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. Descend to the silo walkways, equipping your bolt-action weapon to counter electro anomalies. Proceed left along the silo to activate the device.
Activating the device attracts Bloodsuckers. You can choose to fight them or evade them to reach Mongoose.
The Confrontation with Yaryk Mongoose
Returning to 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 significantly impacts the game's progression. Killing Mongoose allows looting the Malachite pass; choosing the peaceful option yields the pass and some coupons. The pass provides access to the STC Malachite base, unless already obtained through main missions.
