Camera Tool for Dota 2, uses pattern scans so should work for future patches if there isn't any major code changes.
Zoom - Change the Max Zoom, No Zoom artifacts.
Range Display - Enable the recently patched dota_range_display console command.
Field of View - Change Camera FOV, breaks Y rotation angle a bit.
X Camera Rotation - Rotate camera around the X axis, tick the box to hotkey this to Lshift and use mouse to rotate.
Y Rotation Angle - Change the rotation the camera takes when zooming in/out, set to 60 for pure zoom in/out without rotation, similar to LoL.
