What Is ESP in Games? How ESP Cheats Work

ESP is the most common cheat feature in competitive shooters, and the one most players mean when they say someone is “walling”. It does not move your aim or touch your inputs. It shows you things.

What ESP means in games

ESP stands for extrasensory perception, the paranormal idea of knowing something without seeing or hearing it. In games the term was borrowed for exactly that effect. With ESP on, you know where the enemy team is, who is low on health and which room holds the loot, even though nothing in your line of sight tells you.

The name stuck because it describes the result, not the method. Two ESPs can work in very different ways underneath and still both be ESP, because both give you information the game meant to hide.

What an ESP shows

Most ESP menus split the information into toggles you can turn on and off. The usual set:

Survival and extraction games add a lot more on the world side. A Rust build marks ore nodes, crates and sleeping bags. An Escape From Tarkov build marks extracts, quest items and loot by value. That is still ESP: information the game holds, drawn where you can see it.

How ESP works

Every ESP does the same three jobs, in order.

Reading what the game knows

To draw the other players on your screen at the right moment, your game client has to know where they are. The server sends positions, health and equipment for the players near you, and the client keeps that data in memory so it can animate them the instant they come round a corner.

An ESP reads that data. A software cheat reads it from the game’s memory on your PC. A DMA setup reads the same memory from a second device so the reading happens off the gaming PC. Either way, the information was already on your machine. ESP does not hack the server or pull data the game never sent.

Turning world positions into screen positions

A player’s position in memory is a point in the 3D game world. To draw a box around them, the cheat needs to know where that point lands on your 2D screen. Games already do this maths for every frame they render, using the camera’s position, angle and field of view. The ESP reads the same camera data and runs the same projection, which is why the boxes sit exactly on the player models and move with them.

Drawing the result

The last step is putting the boxes on screen. Some cheats draw inside the game’s own rendering. Others draw on a separate transparent layer above the game, which is what an overlay is. A layer like that is also why the display mode matters: exclusive fullscreen can hide it or make it flicker, so most builds ask for borderless or windowed mode.

ESP, wallhack and radar compared

The three words get mixed up because they all show you where players are. The difference is how.

In practice most menus combine them. The ESP tab draws through walls, so it is a wallhack too, and the radar sits in the corner for the moments you want the screen clean.

What ESP cannot show you

ESP is only as good as the data your client receives. Some games limit that data on purpose:

• Server-side culling. The server stops sending a player’s position until they could plausibly become visible to you. Riot’s Valorant is the best-known example and calls its version fog of war. Against a system like that, an ESP shows players late, or only just before they round the corner.
• Distance limits. Many games only stream players within a set range, so a player across a large map simply is not in memory yet.
• Hidden state. Information the server never sends, such as a player’s exact inventory in some games, cannot be drawn because it is not there to read.

This is why ESP quality varies so much from game to game. In a game that sends the whole lobby to every client, a good ESP shows everyone. In a game with aggressive culling, even the best ESP shows less.

Is ESP detectable?

There are two separate questions here, and they get different answers.

The first is whether the anti-cheat can find the cheat software. That depends on the anti-cheat and on the cheat, not on the feature. A public ESP that thousands of people download is usually detected quickly. A private build that changes its signature and is updated when the game patches lasts far longer. No method is ever guaranteed, which is why live status exists. Our page on how anti-cheat detects cheats covers this in depth.

The second is whether other players can tell. ESP changes nothing about how you move or aim, so a spectator only sees it if your behaviour gives it away. Tracking players through walls with your crosshair, pre-aiming every corner and never checking an angle you would normally check are the usual tells. Players who use ESP for information and play the fights themselves rarely look any different from a strong player with good game sense.

Common misconceptions

“ESP sees everything.” It sees what the game client knows. Games that cull positions server-side limit it, and some information is never sent at all.

“ESP is safer than an aimbot because it does nothing.” It is quieter in replays, but the anti-cheat checks for the software, not the feature. A detected build is detected whatever you had switched on.

“ESP slows the game down.” A well-made overlay costs very little. Turning off elements you do not use and lowering the draw distance keeps it light on busy servers.

“Spectators can see the boxes.” The overlay draws on your screen only. What spectators judge is how you play.
