Rubick's cube

Akim agrees to give you flashlights for Miner if you bring him a particular trinket - the Rubick's cube - from a stash in Dark Valley, somewhere at the bandit base.
This quest has a playing card from Kuznetsov's deck.
== Walkthrough ==
Seems like you're not the only one hunting for this seemingly useless trinket, as Dark Valley is filled with military, with two of them carrying RPO-A. There are also 3 BTRs on the road to the bandit base. One of the militaries at the [ gas station] is carrying a playing card. Another one (their commander) will have a PDA with the top secret order to attack the bandit base and secure the Rubick's cube.
The approximate location of the stash with the cube is shown on your map. The exact location is shown on the picture below.
Open the stash just to find no traces of the cube in it. Instead, there's a note demanding payment for it, from some Khazar.
Bring the note and commander's PDA to Akim. He will say that some stalker named Khazar tried to sell him this cube, claiming it had a code to access one of the labs in the Zone. He didn't buy it, after which Khazar went to the Dark Valley. As to flashlights, he will give you the information on a stash with them, in X-16.
== Notes ==
* You can avoid bringing an RPG-7 for BTRs by entering the base through the [ sewers], picking the stash up and using the PTRD from it against them.
* The soldiers are armored and very aggressive. They will push into the base and murder everyone inside unless you intervene quickly.
== Bugs ==
* Skimpy can be killed by the soldiers to the South of the base through the open windows if you don't take care of them quickly. Skimpy himself won't try to hide or evade the shots, just standing there taking hits until he dies.
