Stalker 2: For Science! Side Quest Walkthrough

In Stalker 2: Heart of Chornobyl, players can embark on a side quest titled "For Science!" This quest, a relatively short but rewarding endeavor, grants access to the STC Malachite facility.

Initiating "For Science!":

The quest begins at the Central Elevator in the Chemical Plant. Upon approaching, players will hear Yaryk Mongoose contact Skif via radio. Locate Mongoose on the first floor of the building (easily accessed by vaulting a railing after ascending the rusted stairs). He'll explain the need to activate a second measuring device located atop a nearby silo. Agreeing to his request officially starts the quest.

Reaching the Silo's Peak:

Ascend to the building's roof, dispatching any rodents along the way. Exit through a broken window and descend a ladder to the silo walkways. Be prepared for electro anomalies; equip appropriate gear. Proceed along the silo's top to activate the second device. Activating the device will attract a group of Bloodsuckers. Players can choose to fight or evade them.

Confronting Mongoose:

Return to Mongoose. He'll explain the unforeseen consequences of the experiment. Players can choose to kill Mongoose or accept the reward peacefully. Neither choice significantly impacts the game's progression. Choosing the peaceful option rewards the player with the Malachite Pass and some in-game currency, granting access to the STC Malachite base (if not already accessible via the main storyline). The Malachite pass can also be looted from Mongoose's body if he is killed.
