HaloMods "Classic" Read-only Archive

i know u can somehow play halo not in full screen but i dont know so can u help me?

I assume that you have a shortcut on your desktop of HPC. Right click it, and go to Properties. You now have to edit the Target path and add a few extra commands.
Basically, make it look like this:


Add:
-window
-width 800
-height 600

Hit 'Apply', then 'Ok'.
Now double click the shortcut to Halo and the settings should be applied.
