Warning: Warcraft III 1.27a+ does not currently work on Linux with w3l! This solution is still work in progress. This means you can't play on our server on wine Linux at the moment.
Fedora 25 instructions
# First login to X11 session, NOT Wayland
sudo dnf install wine
sudo dnf install winetricks
winetricks vcrun2013
winetricks vcrun2015
# Download installer, run it normally
At this point everything should basically just work except w3l will fail to start due to failed patching. We are still looking how to fix this problem.
