CS2 has changed the reload mechanics

Valve has reworked reloading in CS2: now, when reloading a weapon with a magazine, all remaining rounds are discarded, and a full new magazine is taken from the reserve. Reserve ammunition is displayed as the number of magazines.

Valve has also added special guides that show how to properly throw grenades. These guides can be used during the first five rounds of each half.

Playing community maps with friends has become easier: you can now join custom matches through the in-game lobby without the console.
