The game is great, it's getting constant updates to surpass cs:go, but the community is horrible, people don't want to cooperate.

I could talk about this game endlessly, but it's best to just play it. It's an incredibly interesting and addictive game. Can I recommend it? Sure, even though Rise is already available. A lot of content, interesting mechanics and just a beautiful implementation left this game in my heart forever.
