Okay, I got a nice fast NEW pc.
It got no plugins, only internet.
I dled cs2d and it keeps saying "Connecting to USGN server"
And I'm 100% sure my internet works, because on my other PC... Cs2d works fine, it loads to the menu.

And I'm wondering if CS2D needs any plugins, or PC standard Requirments

Well, you can compare your computer information with CS2D's System Requirements.

To get your PC information:

don't worry about that
just click the screen a few times or wait a bit

My pc lags and doesn't respond.

Check you firewall settings

Did you install your LAN card drivers? graphic card drivers? any drivers? Especially LAN card and graphic card drivers are needed to play cs2d!

I had the same when my firewall blocked it. It didn't block when I ran it in window mode, and therefore I could set my firewall.

u see servers ?
i have this problem but when i press option my usgn back lol i don't know why .
