After gathering feedbacks from players from all over the world, Valve added a new game mode to matchmaking and offline play: Deathmatch.
Deathmatch mode can be played in Classic, Demolition, or Arms Race maps, and Hidden Path points. There are also a bunch of patch for the weapon, such as increasing kill rewards with the AWP from $50 to $100, to dropping the price of Molotovs and making changes to the recoil. You can view more of the patch notes here.
Deathmatch mode is also a useful way to explore and learn a new map while you try out the new weapon fixes.
They also have launched the private beta for workshop maps. If you’re a map maker, feel free to submit your work to the Steam Workshop for player approval.
