Some guy got mad at me when I accidently flashed the team.
I kept throwing flashbangs at him and he wouldn't stop raging.
It was a good day.
I went 6-15 that day.

Well CSS, What can I say, I love you. If it wasen't for CSS, I don't even know where I'd be in the gaming world today...Probably playing CoD or some nonsense like that! CSS is a game that you can spend hours on. HOURS. There's so many different game servers and mods to choose from! My personal favorites are DeathRun, GunGame DM, & Climb! Of course there's plenty of other ways to play the game as well! I've spent my fair share playing Hide & Seek, Jailbreak and even just Competitive! All around and fun game!
