A brand new patch for Counter-Strike: Global Offensive has just been rolled out by developer Valve, which makes some big changes to the first-person shooter, from the return of classic map Train to major nerfs to the CZ75-Auto pistol and plenty of other tweaks, such as the enabling of the holiday mode.

CS:GO has been around for a few years already and its popularity doesn't show signs of stopping, as thanks to major eSports competitions, such as the recent Dreamhack Winter, not to mention constant updates from Valve, the game is amassing fans all over the world.

A fresh update is now available with big changes

Now, a brand new patch just been released by developer Valve, and the studio has stayed true to its word from last week, as it's a big update with plenty of changes to the multiplayer-only first-person shooter.

First up, veteran fans will enjoy the return of Train, a classic map that was a part of the standard rotation a few months ago but was retired so that Valve could work on it and give it a new lease on life. The revamped version features plenty of major changes and is available currently as part of the Operation Vanguard map group, which is offered for free to all owners of the game.

Besides the returning map, the update for CS:GO makes some key changes to the controversial CZ75-Auto pistol, which was introduced earlier this year and made a big splash due to its overpowered nature.

Thanks to the patch, the magazine size of the pistol has been reduced to just 8 bullets, from the original 12, but it now comes with 3 magazines in total. Its damage and fire rate have been "reduced slightly" according to the studio, while the draw animation is twice as long, showing an extended process of locking and loading. The kill reward has been reduced, while its description has been updated.

Other tweaks are also included, while the holiday mode is turned on

The patch also makes some tweaks to a few other weapons, as the M4A1-S now has a steeper price of 3100, while the Desert Eagle is cheaper, at 700. The Tec-9 firing sound has been updated, while the M4A1-S muzzle flash should no longer be seen through smoke.

Errors with the bomb defusal process on ledges are eliminated, while players should no longer receive money after the first round if they didn't earn it.

A few other bugs have been squashed, while the winter holiday mode is once again in effect, meaning you'll get to see snow on the main screen, as well as freeze-cam borders. Gifts can also be purchased and offered to those in your match.
