The Agroprom Underground is a collection of tunnels and rooms beneath the Agroprom Research Institute and connects to two places in that area - west of the first installation (outside the broken wall) and inside the walls at the second installation. You'll be able to find alot of things here, including artifacts, bandits, mutants and of course Streloks Stash.
Personal Notes
Shadow of Chernobyl
The Electro anomaly (found in the tunnel directly south of the entrance) in the Agroprom Underground can be a gold mine for artifacts, if one chooses to go down there after midnight.
Clear Sky
The Agroprom Underground has no artifacts, and not many valuables at all. You can get some stash info from people above ground, one of the stashes has an OG-7v warhead, another has 7.62 PP ammo. A room near the Controller has some health items and ammo, including a Medkit, two Army Medkits, a Scientific Medkit, 5.56x45mm SS109 bullets, and 5.45x39mm FMJ bullets.
Enemies & mutants
Shadow of Chernobyl
The Agroprom Underground is home to Bandits, Bloodsucker, Military and even a Controller.
Clear Sky
On your first time in the Agroprom Underground, you will encounter Bandits. If you are totally neutral or slightly hostile to the bandit faction they will open fire on sight. If you are slightly friendly to the bandit faction, they won't give you any trouble . Prior to the Bandits you'll encounter several Snorks, and a Controller. Some Rodents appear underground, but they are not hostile. Near the exit, you'll encounter four Pyrogeists. If you choose to return to the underground, you'll find Duty members. Whether they're hostile to you or not depends on your status with them.
