Every time I try to open Shell Shock Live on steam, the spinning gear never hits the ground, and I can't join. Also, the sound completely cuts out, but the gear keeps on falling and spinning.
By "My Internet", do you mean my modem or my computer? Because I restarted my modem yesterday, and my internet is working fine on my computer. Also, I tried plugging in an ethernet cable to my computer, it didn't work.
I don't know how to help you. But I found this: http://steamcommunity.com/app/326460/discussions/0/535152276592290037/
Was about to say i didnt have unity yet my game works... umm have you tried verifying the files in steam/reinstalling?
I really wish they would be able to fix this issue. It's a really great game, but they can't make it playable.
