Are they broken? It shows Pipboy achievement pictures from New Vegas for TF 2 achievements.

Carmack of course!

Check out S4 League, it's a TPS and only use TCP. Also I can play it with 20-50 ms.

I had tried that before yeah but what I was looking for is actually a FPS or TPS. There aren't so many like you said though. :(

Thanks anyway.

No, it's not blocked but I hate those casual Facebook games.

btw all Blizzard games -including World of Warcraft and latest StarCraft II- are only using TCP :D. There might be someone who wanna know..

Well, I'm behind a hardware firewall (university LAN), and all UDP ports are closed. Luckily TCP's are open :), but there aren't many MMO's or MP games, especially TPS and FPS ones that only use TCP. I've found a MMOTPS called S4 League for example, it can be played well with closed UDP ports. So I wanna ask if there are more like that. Thank you.
