Operation Hydra came after a huge delay and gap in the CSGO Operation calendar. Valve has announced that the operation will be extended till November 13th and will feature a 50% discount based on this extended period. CSGO has seen new players coming in and this will give the new players an opportunity to get a taste of the Operations in CSGO.
Some of the features in the Operation will continue to stay on in the current form. This will also include a few maps from the Operation and what can only be construed as an update to the CSGO Competitive map pool .
After Operation Hydra ends, some of its most popular features will live on.
First, the most-played operation game modes during the final month of the operation will be added to CS:GO. Second, the most played operation maps of the final month in Competitive Matchmaking and Casual (currently Agency and Austria, respectively) will replace the least played maps in those modes.
