What does a Wardogs wallhack do?

It's the ESP overlay in Wardogs Hack: enemy operators and vehicles drawn through walls, with distance readouts, health bars, vehicle cues, and categories you can flip on or off.

Same feature, two names

Wallhack is the older word for what the menu calls visuals. Nothing gets rendered transparent. The overlay draws marker geometry on top of the frame, at coordinates the engine already exposes. Walls still look like walls, so the tell is a box where a person is standing, never a hole cut into the building.

Why that shows up in how you play

Seeing a position through a wall doesn't hand you a shot through it. What it hands you is routing: which door is watched, whether a squad is stacked in one room or split across two, whether the hallway you're about to walk down is occupied. All of that counts in the seconds before contact, not in the firefight itself.

Staying believable

The classic tell is acting on information you couldn't visibly have. Pre-aiming a wall, tracking a player through a building, spinning to meet a flank before it makes a sound: any of it looks awful on a killcam. Cut the range down, leave a few categories off, and let the overlay inform positioning. It doesn't aim for you, and it shouldn't look like it does.
