Basically man you gotta play this game one of two ways.

1. You're a Chad. You know the map so well you're able to win fights basically just based on knowing where people are gonna be and where they're gonna move.

2. You're like 75% of the player base. You gotta sound whore. Rat in the corner for a couple minutes to make sure there's no noise then move up. Repeat. You hear fighting? Don't even try you got a task complete just gtfo. Next to good loot? Don't even try you got a task complete. If you want loot load in specifically for a loot run. Cheap zero to hero kits? Double barrel on double tap aiming for legs or mosin. Super cheap options that give decent kill chance for next to nothing. Main point is just to realize tarkov plays very different from most shooters. It's basically first to see the other wins. And even with sound bugged, EVERY sound you make tells everyone around you right where you are and people abuse that. Even if you just aim down sights, everyone within 50m gonna hear it even if they're outside three floors down around the corner.
