For any newbies, make sure you download the custom maps created by the community before playing on the Workshop Servers. Might take awhile to download and integrate into the game as there are 20+ maps now approved. The entire list can be forund here.
Also, another big game patch is incoming in the next few days so keep your eyes out for what's included. Patch notes will be on the H-Hour SteamHub and the forums.
