ESP features in Escape from Tarkov
ESP features are Wallhack features that provide various information about enemies and loot through walls.
Typically, each developer displays the features they consider necessary. For example, the BOX feature — no cheat goes without it — this outlines enemies in a box. If there's a feature to show visible and invisible targets, it becomes even more convenient.
Features can also show what weapon a person has, their health, their K/D ratio, and much more, giving you a clear understanding of whether someone is dangerous, if they're a cheater, where they're looking. Typically, when a cheater sees another cheater, they greet each other through walls and don't bother each other.
One of the most useless ESP features is lines that go from you to the enemy, but maybe it helps someone!
Loot also falls under ESP features since you can see it without even looting a bag, jacket, crate, etc. Some cheats also draw backpacks of killed players. In premium cheats, loot can be sorted by value, which helps save time on looting certain lootboxes. Or simplifies searching.
Some cheats also include the ability to change the color of loot or specific objects.
Simply put, ESP features have no settings — you just check a box and ESP displays the needed feature.
