Help the Ecologists take measurements

 is a storyline task that is assigned in the S.T.A.L.K.E.R.: Lost Alpha standalone mod.

"Ah, an eager stalker. Good then, you can go meet my field agent immediately, He is in a building nearby. I'll mark his position on your PDA. Fair warning: there seems to be something causing psy-emissions at the old bus station. We need to know what's with that. Best to take measurements there and kill two birds with one stone."

- Mission briefing

Overview

 * This is a four-part mission that has many opportunities for failure.
 * Initially, there is no pressure until the first objective (the field agent) is met, afterwards events become 'dynamic' and combat saves may be needed.
 * The mission rewards may be compromised if the Field Agent succumbs to one of the several dangers present during the mission.
 * Returning with the results to the Ecologist Contact concludes the mission.

Trivia

 * The PP-4a sensor that is lost from the player's inventory presumably belongs to the Field Agent (v1.3003)
 * If a high grade rifle such as a Sniper rifle SVDm-2 is left in the open, then the Field Agent will probably swerve across and pick it up on his return trip. It will not be available for trade.
 * The Field Agent will continuously repeat the mission objectives by himself and progress his objectives if the player is next to him, as well as saying the same dialogue to the player, even though the mission was just completed (v1.4005).
 * Neither the Ecologist contact nor the Field Agent have stable bio names.
 * Successful completion of this mission grants one skill point point and Data on measurements of anomalous fields tech upgrade for armours. (v1.4005+)
