Big one. Basically doubled the mod in size, so here's the rundown.

New dimensions

Klondike — a separate closed-off dimension that acts as a reward vault. Has its own drop table, way rarer than the overworld, and the only place you'll ever see a Unique-rarity artifact. Valhalla — another dimension, built around trading and NPCs. You get there through portal bubbles scattered around the new biome.

Red Forest biome New biome with its own look (rusty pine needles, leaf litter piles), a ruined village, and a DUGA radar array (ZGRLS) you can find loot in — including a blueprint item that only spawns in the radar control building.

Trading is a whole thing now Added actual trader NPCs with a shop UI, a basket/buy-all system, and reputation that scales your sell prices up the more you trade. Currency is Rubles. Also threw in ambient "stalker" NPCs just wandering around for atmosphere.

Artifact economy got way deeper

Proto-artifacts + a Proto Converter block to farm them from clusters (has states — running, no fuel, burned out, cooling down) A Research Station to unlock random positive traits on "Unknown" artifacts, using a serum + energy, with a reset option if you want to reroll Artifacts can now break and get repaired with matching-rarity proto-artifacts Sarcophagus item that buffs everything sitting in the same container New stats panel showing your totals (armor, health, regen, speed, stamina) at a glance

New anomalies Electro, Haze, Rot, Spark, Vent, and the Proto-artifact Cluster, plus the two portal bubbles (Klondike/Valhalla) that teleport you on entry.

Stamina + food buffs Stamina is now its own system with a HUD bar and server-side checks so people can't just hack around it. Food buffs got their own icons/overlay too.

Random extras Jukebox radio, dedicated Klondike music, toggleable ZGRLS electric visual effects (client-side, per-player), new commands for valhalla/protocluster/zgrlseffects.

Cut / changed

/anomalyzone locate is gone Most of the old crafting recipes (batteries, food, injections, steel plates, etc.) got pulled — that stuff is meant to come from the trader/converter/research loop now instead of being craftable

Net result: ~110 new classes, way more localization strings, three new dimensions/biomes worth of structures. Not really a "point update," more like a second game bolted onto the first.
