Unusual controller

Sviblov wants you to bring the brain of an unusual controller spotted at the boat station in Swamps, for the Clear Sky to be able to research it.
== Walkthrough ==
After coming to the [ boat station], it becomes clear that the psi radiation is so strong in this place that it can kill you in seconds, unless you have a closed loop suit and a couple Symbions to max out your psi resistance. Turns out, there are 3 biomasses hidden in the bushes, besides the unusual controller and another controller.
=== Head-on attack ===
A head-on attack will be significantly easier if you clear the boat station from the usual fauna before accepting the quest. It's typically inhabited by 3-5 controllers, a couple parasites that can make you sick with plague, a couple exploding zombies, a couple ghostly zombies which spawn ghostly flies, and a bunch of mosquitoes and frogs. Fighting all that while also fighting the unusual controller and biomasses can be the worst experience in your life.
The location of biomasses is presented on a picture. Kill them first, preferably with anomalous grenades but melee weapons or shotguns are also good for this if you know exactly where they are and have full psi protection.
=== Sniping ===
 
In a typical OP-2 fashion, the biomassses won't spawn until you approach the boat station. You can walk through the [ gap in the fence] (1), then touch the station fence from outside to spawn biomasses (2), and run towards the [ hidden cave] to climb to the top of the railway bridge (3). Then you'll have a great vantage point to snipe all three biomasses and other enemies at the station.
Collect the Red Controller Brain from the unusual controller, harvest the parts of the biomasses as well, and report to Sviblov for your reward.
== Notes ==
* If you accepted the Rabbitfoots quest from Kuznetsov, approaching the hole in the fence will spawn a psionic and a horde of zombified stalkers, one of which is Polecat, one of the two fugitives. These are not part of this quest.
== Bugs ==
* After clearing out the camp before accepting the quest, sometimes the red brain controller will not spawn. Reloading the save does not fix the issue, but leaving the swamps and returning will fix this.
