In Stalker 2: Heart of Chornobyl, Dr. Shcherba's request for help initiates the side quest, "In The Name of Science," tasking players with retrieving electronic collars from various mutants. This comprehensive guide details the quest's progression, crucial choices, and potential outcomes.

Locating the Electronic Collars:

This mission requires finding five collars scattered across The Zone. Their locations are:

Returning the collars to Shcherba at the Roofed Warehouse in the Chemical Plant triggers the next phase. If you've previously acquired and sold these collars, the quest might bug. Use the console command "XEndQuestNodeBySID E08_SQ01_S2_SetJournal_WaitForSherbaCall_Finish_Pin_0" to resolve this.

Jammer Decision:

Shcherba discovers a signal jamming the collars. Players must investigate the Storage on the Hill, encountering various enemies before reaching the jamming device. The choice is:

• Destroy/Disable the Jammer (Recommended): This advances the quest, rewarding players with coupons and leading to a confrontation with bloodsuckers and a subsequent choice.
• Recalibrate the Jammer: This concludes the quest with a coupon reward from Dvupalov.

Final Confrontation and Choice:

Disabling the jammer leads to a call from Shcherba, followed by a meeting at his lab. Players receive Magic Vodka from Dr. Dvupalov, then encounter a trap, PSI-radiation, and three bloodsuckers. The final choice is:

• Kill Shcherba: Results in the same rewards as the next option.
• Let Shcherba Go (Recommended): Maintains positive relations with scientists and Dvupalov.

Both choices yield the Gauss Gun reward from Dvupalov and unlock the "On a Leash" trophy. Choosing to let Shcherba go is generally advised for maintaining positive relationships within the game's world.
