Yes, the way to do this should take a few simple steps. I have only tried this on older Warcraft III versions prior to Reforged, but for Reforged the steps are probably the same:
- Download and install the Warcraft III (and log in if it is Reforged) when you have internet prior to leaving on your trip. That way, the game should allow you access while offline. If for some reason Battle.net tries to block you from doing this, use command prompt and use the two steps (a)
cd C:\Program Files\Warcraft III\_retail_\x86-64\to get to the Warcraft folder (it might be in Program Files (x86) if it says folder not found) then (b)".\Warcraft III.exe" -launchto launch to the Reforged menu in a way that skips the Battle.net launcher. (If your Battle.net launcher is working fine in the offline mode, maybe you can skip all this.) - Now that you are in a remote region of planet Earth with two Windows notebooks that have Reforged (or your preferred Warcraft III version) installed and verified, you need to connect them together. If you are on Windows 7 or earlier there is a way to spawn a WiFi LAN using computer software on your laptop. However, for Windows 8 and above, Cisco or one of the other router companies paid Microsoft a good amount of money or something to make Microsoft remove this feature to promote the falsehood that hosting a WiFi LAN network requires a specialized hardware. Whatever they did, though, it worked. So, this is where I use an Android phone. On the phone, go to the “Mobile Data” option and turn off the Mobile Data. Then, go to the “Wireless Hotspot” button and activate it to create a hotspot using your phone. (Again, if you are on Windows 7 or below you can skip this step and create a WiFi LAN access point using the system menus of Windows.)
- Now that you have created a WiFi LAN access point that exists but offers no internet connection, you can connect both Windows notebook machines to this WiFi LAN access point. While connected you will have no internet, but this is expected.
- Open the Warcraft III on each of the machines and enter the Local Area Network menu. Host a game using one of the machines, by clicking the “Create Game” button.
- Open the Warcraft III on the other machine and enter Local Area Network. You should see the game that was hosted by the other Windows machine. Click on it and join it as you would normally.
This has worked for me in the past to play multiplayer LAN Warcraft III on those remote regions of Planet Earth when you have no access to internet. Remember, of course, that if you are going to be out there for more than 30 days then you need to use a version of Warcraft III from before Reforged released, because the Patch 1.32 program is set to self-terminate after 30 days of being offline (or so I’m told. I haven’t had the opportunity to run into that problem yet).
