I recently found this miraculously in my Steam library, so I gave it a go. This video shows, what I experienced:
To be fair, I like Counter-Strike. But I'm so bad at it. I just can't get better. That's why I love playing Zombie mods or other stuff, that mostly doesn't need skill.
The game itself feels weird. It's no Call of Duty, but neither a real Counter-Strike. Maybe they'll patch some stuff. It's a beta still.
Also I hate the buy menu. God damn console crap.
