In this small guide I'm going to teach you how to launch a different exe. for a game through steam then what steam uses as the standard launcher.
This is mainly useful if you use a mod manger, that requires you to launch the game trough it.

First locate an exe. that you want to launch and make and shortcut of it, then right click on the shortcut and go to properties and copy the target line

Then we need to head to a game and get tot the launch option.
We can do that in 2 ways:

1- Right Click on your game, Go to Properties
2- Click on the cog symbol on the right side, Go to Properties

Then set Launch Options... and enter this command below:

"Full game path to Game.exe" %command%

Including the '' symbols in front and at the end and a space between '' and %command%
it would look like this:

"C:\Program Files (x86)\steam\steamapps\common\Fallout New Vegas\FalloutNV.exe" %command%


You now can delete the shortcut, as the target line is aimed at the exe. that you made the shortcut for.

Why would we need something like this?!

I made a couple guides on how to mod Call of Duty plutonium offline, Call of Duty isn't the safest to play online and I didn't want to play against other players, but I do want to have the progression online like but against bots.
In those guides we needed to replace certain files that get automatically restored whenever we start plutonium because it does an auto update and repair of files.
And we don't want to risk going into the base game to get a potential infection.
But we still like to use steam as a starting point to launch our games.
For this example I will use Call of Duty: Black ops 2
I installed the Lanlauncher on my desktop in a separate file.
So If we apply the new knowledge we can start the Lanlauncher by clicking play Black ops 2.
The settings will look like this:

This can also be used if you have to launch the game trough a mod manager.
