So while playing the console I stumbled upon this nifty way of extending the d2 camera zoom range.
This takes advantage of a console command which allows readjusting the time needed for the camera
to reset to its normal distance. Enjoy.
Avoid moving camera by dragging the selection polygon using minimap. This cancels the effect.Prerequisites: Enable console with the launch parameter -console
1) Add your character to a control group
2) Open console and type in dota_camera_smooth_time 9999
3) Move your camera to the top-left corner of the map
4) Re-select your character with the control group hotkey
To make this glitch semi-persistent, add the line above to your autoexec.cfg.
