==How to run 2 ArmA on the same PC==
A fast way to setup MP missions is to run two ArmA games on the same computer. Let's call the first ''Editor'' and the second ''Client''.
''Editor'' run the mission editor, selected clicking on ''Multiplayer -> New -> Edit/New''.
''Client'' can now join it selecting ''Multiplayer -> LAN'' or ''Remote'' wiht IP ''127.0.0.1''. It will see ''Editor'' in edit mode.
As ''Editor'' clicks on ''Preview'' to run the mission, a PBO named <tt>__cur_mp.pbo</tt> is create on the fly for ''Client'' to be downloaded.
Both now enter the usual lobby and choose the slot they want. They play the mission, and when they leave back to the lobby, they can choose to run it again or go back. ''Editor'' in this case to the mission editor, ''Client'' to the multiplayer or ''Wait for host'' screen.


In order to avoid to click the menus, command line arguments are available.
For ''Editor''<pre>
\ArmA\arma.exe  -host
</pre>
For ''Client''<pre>
\ArmA\arma.exe -connect=localhost
</pre>
I like to suggest adding<pre>
-window -nosplash -world=empty -nopause
</pre>to speed up things and run safe from alt-tabbing.
===Problems===
All of this above should works if ArmA doesn't check for duplicated CD keys, and you have a single operative system user and a single installation of ArmA. You maybe know that there is an option in [[server.cfg]] called [[server.cfg#Server_Options|kickduplicate]], which if set to 0 allows the same CD key to join a MP game. The problem is that server.cfg, or better, the file you provide with [[-config]], is only read if you run ArmA with [[ArmA:_Startup_Parameters#Network_Options|-server]] or the dedicated <tt>[[ArmA:_Dedicated_Server|arma_server.exe]]</tt> or <tt>server</tt> on [[ArmA:_Dedicated_Server#Linux_2|Linux]].
Because this check is done online at gamespy, if you drop your internet connection, the check isn't done. But this could be a problem, because while editing or testing, you usually want to search some forums or other online resources.
