As the title says, I'm looking for a way to run Arma 2: OA with BAF, PMC and ACR DLCs without running steam.
Is there a way to do it?
As far as I know there are 3 ways to select or deselect mods/DLCs in ARMA 2 and play it without Steam:
I think you can start ArmAOA.exe straight from Windows Explorer (I assume you are using Windows). As for starting it with BAF, PMC, ACR, you are going to need to add some parameters to start it up.
The best way to do this, is to open up windows explorer (My Computer or whatever) and in the navigation bar, to type "C:\Program Files (x86)\Steam\steamapps\common\arma 2 operation arrowhead" (if necessary replace C:\Program Files (x86)\Steam\ with the Steam installation folder). Next, right click on ArmA2OA.exe and choose Copy and go to wherever you want a shortcut to appear and right-click and choose Paste shortcut. Now, on this newly created shortcut, right-click it and choose Properties and add the following to the end of what currently exists in the text box labelled target:
I'm unsure whether this is the correct syntax (athough I'm pretty sure it is) but I can't test this because I've not got my PC with me at the moment, and also I don't own ACR yet and I'm just guessing that its folder is going to be called ACR. But, try this and get back to me with the results.
