Peut être une solution à L4D multi ?

! you people never learn do you?

IF you want to host game over internet:
- install hamachi!
- join private room (invite some friends).
- set them aliases (so their ips will be c-class compared to yours).
- run game and enable console in option menu!
- type "maps *" in console to get full map list of the game!
- choose one map and type "map map_name"
- the server is started

(dont know if it work without hamachi! try set sv_lan 0 and your friends type in console "connect ip" ip is your ISP ip)

IF you want to join game ove internet:
- install hamachi!
- join private room (you were invited to)!
- run game and enable console in option menu!
- type "connect hamachi_ip"

(hamachi_ip is the ip of player who created the server)

and uala no more you must connect to steam bull****

REGARDS!

The engine.dll files only work when you're the one hosting. It removes the steam validation check from YOUR copy. When somebody else is hosting, your engine.dll file isn't being used, theirs is.

Solution? Start your own lobby.

You can play with anybody, as long as you're the one hosting. Start a "Play with Friends" lobby, then switch the permissions to public. Start the game.

You need to have Steam installed, then go to "My Games" -> "Add non-steam game"
Then choose your non-steam Left 4 Dead.

This is after you've copied the multiplayer fix (engine.dll) into your Program Files\Left 4 Dead\bin folder.
You might want to save your original engine.dll in case it crashes.

I downloaded the English Language pack, multiplayer fix from post#48 and everything works. just gotta run it through Steam.
