[HL/Opfor/DoD] Thirdperson Exploit in Multiplayer #2622

Open BlackShadow opened 5 years ago

BlackShadow commented 5 years ago

Hi,

There's a thirdperson exploit allows player use thirdperson in Multiplayer. Normally thirdperson mode disabled in Multiplayer.

> Exe version 1.1.2.6/Stdio (valve)
> Exe build: 16:01:05 Jul 20 2019 (8304)

If player types thirdperson in singleplayer and creates a LAN game or joins a server, the game doesn't reset the thirdperson to firstperson.

This issue occurs in these games:

Half-Life Half-Life: Opposing Force Day of Defeat

Also here's a footage of this exploit:

With this thirdperson exploit you can wallhack in multiplayer.

Also extra thingy: If player select singleplayer mode after joining a LAN/Internet game, pausable command stays in "1". And this results the game doesn't pause when player press ESC.

Tested on Half-Life 1 after the new 25th anniversary update and the issue still persists, to reproduce simply join any multiplayer server with sv_cheats 0, then type the following in the console disconnect; thirdperson; cam_idealyaw 0; retry;.
