While exploring The Zone in *Stalker 2: Heart of Chornobyl*, players will encounter a variety of NPCs that can lead to engaging side quests, such as the "For Science!" mission. This quest begins when Skif meets Yaryk Mongoose, who tasks players with activating a second measuring device located atop a Silo. Though relatively brief, this mission rewards players with a Malachite pass, granting access to the facilities of STC Malachite.
How to Start "For Science!" Side Quest in Stalker 2
To embark on the "For Science!" side quest in *Stalker 2*, players must first meet Yaryk Mongoose at the Central Elevator within the Chemical Plant region. As you approach the area, Mongoose will initiate contact via radio, urging Skif to ascend the building to meet him.
Upon entering the Central Elevator location, veer left past the conveyor belts and climb the rusted stairs. Mongoose awaits on the first floor; you can vault the railing and enter his room to engage in conversation. He'll point out a nearby measuring device and mention another atop a silo, which needs simultaneous activation. Accepting his request will officially start the "For Science!" side mission.
Reaching the Top of the Silo During "For Science!" Side Quest
After concluding your discussion with Mongoose, exit the room and ascend the stairs to the building's roof. Be prepared to encounter a pack of rodents; dispatch them and proceed to a room with broken windows on both sides. Exit through any window and descend the ladder on the external walkway.
From there, leap onto the connecting walkway leading to the Silos. Equip your bolt to navigate the electro anomalies en route to the second measuring device. Continue left along the silo's top until you reach and activate the device.
Upon activation, a pack of Bloodsuckers will storm the compound. You have the option to either eliminate them or evade them to return to Yaryk Mongoose and address the unexpected danger.
Confront Yaryk Mongoose About the Bloodsucker Pack
When you confront Mongoose, he'll explain the unintended consequences of the experiment. At this juncture, players face a choice: eliminate Mongoose for endangering Skif's life or accept the reward and depart. There are no significant repercussions for either decision, so choose according to your preference. If you decide to kill Mongoose, you can loot the Malachite pass from his body.
However, it's advisable to listen to Mongoose's explanation and opt for the non-hostile route. This choice will grant you the Malachite Pass along with additional coupons. With the pass in hand, you can now access the STC Malachite base, provided you don't already have entry through a main mission.
