The first time, I joined a friend who was describing events that sounded like hacking. He ran into Berezino, and immediately got 'picked up' by a group of about 5-6 players, who for some reason, allowed him to be part of the group. They always knew when people were coming into the Northern (Coastal) part of Berezino, from any direction. When he said they allowed him to 'join' them, and were giving him gear, another friend and I decided to join.
As described, they saw us before we entered town and had an envoy meet us and bring us to a long shed. There, they handcuffed 5 of us and had us face the wall while they killed geared people and gave us gear. They didn't reload a single time while shooting over 100 zombies and none of it was aimed fire. They threw no less than 5 flashbangs, and were never concerned with running out of gear. When they decided to 'let us go' (bed time or something), they had me fully geared up with an M4 with hacked double mags, a flash bang, hacked ammo.
The 2nd event on this server was 12 hours ago. Possibly the same group, maybe different, spotted people well outside the viewing radius, the same group as I'd been with the night prior. They had infinite grenades and were repeatedly blowing them up around the gas station. We sat in place for 15-20 minutes waiting for 3 guys to join us before the action started.
The first member of our team died from someone snapshooting from 200 yards with an M4. I located a guy trying to flank us, so I displaced to pursue him, which ended up being a bad idea. He was blaring techno crap beat with "Get your hands up in the air" repeating, and when I told him to eff off, he started shooting, and missed most of the time. I came around the edge of a building, which surprised him momentarily and emptied about 25 AK101 rounds into him. I went unconscious pretty ticked off, and died seconds later. The 3rd member of our team I'd given an AKM with 75 round drum, and he nearly emptied the drum into a player, and was also killed.
I respawned south of Berezino, and went looking for bodies. There was a dead body next to each of ours, so we'd killed them, but only after they'd put us unconscious (server lag?). I picked up one set of gear, but couldn't put anything into the shirt or bag that this guy had, and the M4 I picked up was missing every part it could (stock, sights, magazine, rail). I tried dropping it, and picking it all back up (that usually works), but got nowhere. The gun was unresponsive, and it was a piece of my wearable inventory (with the axe, glasses, helmet), it never got to my usable inventory (tactical shirts, pants, bags, vests) so it was useless.
I was going to run to my body, until I saw 2 more guys dressed exactly the same as the rest we'd seen and a bambi. Then I started running the direction I'd come, hoping to get away. They shot over 50 times and didn't hit me until the last 3-4, which killed me.
My 2nd respawn, I was in Novo and ran down to find the group. I found them, and also ran into people who'd left Berezino as soon as they heard the shooting because of the volume of fire, it could only be hackers. When we met up, we were on the road between N and S Berezino at the apartments. We stayed inside to bandage from zombies and eat/drink. They threw a grenade into the apartment, and luckily, only my leg was painful. As I ran out, they sprayed again, and I ran around the corner, hoping for some relief, trying to swerve from building to building. They had people on both sides of the building shooting the same direction at me, so there was nothing I could have done. 100 bullets later, I was dead after the last 3-4 hit me.
The 3rd respawn, I was 1/2 way between Berezino and Svetlo. This is where I saw them again, where they played the same techno crap and ran in circles around me until they figured out I didn't care, I wasn't stopping. Then, they shot me about 15 times, only hitting my arms and legs. I bled out, but they bandaged me and brought me back to 'torture' me. I figured if they were messing with me, my buddies could get away (which wasn't the case).
I just crawled around the gas station, hoping it'd blow up and kill them, too. I'll attach the video of that part when it's uploaded.
