Cleaning up

 is an optional series of side missions featured in S.T.A.L.K.E.R.: Lost Alpha.

Overview

 * The mission is given by Major Griboyedov, located at the Military barracks in eastern Countryside.
 * It features a player selected series of four Camp eliminations that take place in the eastern half of Countryside.
 * The missions must be taken sequentially.
 * Each task is asked for by the player, which allows time for repairs, restocking, loot dropping or any other business to be scheduled to suit the player.
 * It is unclear at this juncture if the mission set is repeatable or reverts to earlier segments if left for prolonged intervals by the player.
 * Considerable preplanning is advisable. See the Notes section below.
 * N.B. The equipment issued by the Major varies. If the vanilla game is being played then a Tunder S14 and suitable ammunition is given; the listed rewards below correspond to the PRM Modpack variant. Given armour seems to be identical across versions.

Mission set

 * 1) Kill the Fleshes (two packs)
 * 2) Kill the Psy dog 'flock'
 * 3) Kill the Chimera in the Road Tunnel
 * 4) Destroy the Controller

Cleaning up Part 1

 * The major tasks the player with eliminating a herd of seven to ten Fleshes to the south and places a map marker to indicate their location.
 * He also provides the player with a Vepr-12 Molot shotgun and 45 rounds of 12x70 Buckshot.
 * The player takes note of the extent of the minefield outside the checkpoint and avoids it.
 * Once the infestation is eliminated the major arbitrarily assigns a second fleshpack as a target objective to the north-west. This also contains seven to twelve flesh.
 * Eliminating the herds updates the mission in that the player gets a heads up to "Report to the major".
 * Note that with either fleshpack, the last opponent may attempt to run off to safety, but still needs to be eliminated.

Cleaning up Part 2

 * The second part involves the elimination of around five Psy dogs from a location north of the Water Dam anomaly pit.
 * This will also end with a "Report about the progress" notification upon successful completion.
 * There is a useable anomaly that may assist the player locally.

Cleaning up Part 3

 * The third part is a three-part submission to kill a Chimera at the Road Tunnel that divides the Countryside level into two halves.
 * The mission must be performed at night (after 22.00h)
 * For the purposes of the mission there will be no Bandits in the tunnel.
 * Completion triggers a "Report about the progress" notification, at which point the Chimera's mate will attack the player.
 * Reporting to the major concludes the mission.

Cleaning up Part 4

 * The fourth and final part involves the eradication of a Controller and his retinue of mutants located west of the derelict bus where Bandits are known to spawn in earlier releases.
 * Completion again activates a "Report about the progress" heads up and shortly after this the Bandit spawn occurs near the bus.
 * The player may need to plan for additional bulletproofing for this skirmish if wearing lighter armour.
 * On reporting back to conclude the mission, payment is NOT received by the player as proceedings are interrupted by a significant mutant attack on the Military Checkpoint which takes precedence.
