No Labyrinth Transition

Accessed the caves via Agroprom. Scaled the wall by the two carts. went by the 2nd fire. Walked thru the one-way passage. Hi slope in front of me. Electro to the left and to the right. I go left and get burned by the electro and make it to the corner but I don't see a transition point in the corner or anywhere in this huge cave. No blue transition arrow in this room. I completed the Gauntlet.I replayed this game about 5x's, but can't get to new transition maps other than the basic ones.

IIRC you need to get the rescue Coal mission from Miner before the labyrinth transition spawns. I know I've been there at least twice in my current playthrough (looking for Baldy's treasure and prematurely looking for Strelock's PDA) but no transition is yet present.

OK, thanks!! You guys have really been great in helping us lost STALKERS. in all my play through, I've hit a wall on 3 missions. Finding documents for Kuznetsov, Finding the hiding place in lab x10 and AWP Iglomet for Kalinin with bolts. I would skip them if I knew for sure they did not lead to a new transition. May I tap your brain? Being that you are smarter than Professor Google.

At one point, the Kuznetsov documents are mentioned by him when you talk with him about things other than the Vodka bribe.  The documents require a somewhat delicate mission to Agroprom to secure evidence that could cause trouble for Kuznetsov and his squad.  He rewards you if you bring him those documents.

There are several missions with hiding places in X10.  If you mean the hiding place where you are to collect a stash for Kostya, I believe that the "key" to getting that stash has been covered in these forums.  It's similar to finding a way to Strelok's "stash" in Agroprom Underground, teleports all over the place. Use google translate to visit this French site (if you don't speak French!), they cover the Kostya stash series wonderfully! [You must be registered and logged in to see this link.]

The Iglomet used to be (eventually) available from the Duty trader (forgot his name, in Bar) but I've had to get it from a stash in my Labyrinth wanderings of late.  It may be for sale by that trader at some point, but I've not been able to buy it from him since 16,7 - but this may be because I'm impatient, don't know.
