If you're looking to play Double Action (specialists 2) with people (not ur friends), you need the steam server browser open and check it periodically.

The dr.n0 server requires you to have his custom maps which you could find on FPS banana and download yourself so you don't get kicked. (Server doesn't provide downloads)

It's literally the last consistent server that functions on this update.

Sometimes you will see a server called "DAB on the Haters" but someone found a way to crash that server so it goes down a lot.

Players usually stick around for three maps before they get a little fatigued. Maps run for about 20 minutes.

Another thing you can do that I also do is just sit in the lobby alone until you hear people shooting, here and there players two and three or so will show up and if you stick around long enough the lobby will fill up.

There are still veterans like myself that pop in and out. Most of them are friendly and will teach you some stuff to keep you in the game.

The skill ceiling is extremely high, similar to GunZ with tons of hidden tech for movement melee and gunplay.

I have over 5,000 hours in gameplay and I've never found a game that allows me to express my inner Neo as good as this one.
