It absolutely is. Super fast-paced. Not as active as it once was, but still has an active player base. My favorite servers were the CTF ones with grappling hooks enabled and no weapons except the sniper weapon and the super-jumpy boy weapon.

I played again for a few days not terribly long ago, but my skills have atrophied a lot. I wasn't really able to hold my own. I ought to go back to it some time when I'm ready to put in the effort to get back to my previous skill level.

They've added vehicles and stuff since I used to play regularly. I haven't messed with that any.

So much nostalgia there.
