I love it but I can't play with other people because almost everybody in the game hacks. I'm not just saying that because I suck at CS. It's true. So I just play with bots.
SUre, get the $25 usd pack with gmod or get the $20 pack with dods and hl2dm + hl2LC but i reccomend just getting gmod with it. it's 5 off its a good game too.
