The internet's Fiyenyaa is probably pleased to know that those quests were twiddled with. Developer's Battlestate Games say they have "simplified Jaeger's quests", in addition to EFT Roubles converting diverse different old quests and adding new rewards. Quests in Tarkov are pretty barebones - they have you going to a specific area, or trying to find a selected gun, or simply killing NPCs or players. They give you XP, and levelling up makes you better at an intimidating array of specific things.
There's hundreds else that's new. You can now lean whilst inclined, the NPC AI and positional audio have both been souped up, and lots of tweaks have been made to the "observed in raid" popularity on items. That's large, now not only as it adjustments which equipment satisfies quest situations, but additionally because you can now handiest promote tools which you've observed on a raid. My buddy Alex tells me that "this makes it more difficult for marketplace buyers to flip items and manipulate supply" on the player-driven flea marketplace. They've additionally introduced captcha security, which the devs say you'll want to wade through "if there are suspicious moves at the Escape from tarkov roubles flea marketplace and in the exchange". Even Fiy recognizes this sounds disturbing.
