A new Counter-Strike: Global Offensive exploit has been discovered, which allows players to basically reset either the fire from molotovs, or the shape of the smoke that deploys from smoke grenades. In the most extreme cases, that could allow exploiters to create one-way smokes on official servers with anti-cheat protections, but there are some limitations to how far it can go.
The command resets active smokes and molotovs, giving a different randomised shape for smoke, or making the molotov fire disappear for about a quarter-second. The exploit, discovered by DonHaci on Twitter, relies on the fact that these elements are calculated on the client side.
You can bind the command to repeat the exploit, and in warmups you can endlessly spam through smoke shapes until you get something advantageous. That can potentially include a one-way smoke – a rare glitch that already occurs in the game. During actual rounds, however, the exploit can only be used once.
While one reset probably won’t be enough to get you a one-way smoke, it is enough to pull away a disadvantageous pattern and replace it with something that gives you a better shot on your opponent.
You can see the glitch in action above.
