Dota 2 Mod Manager

Dota 2 item icon mods

The icons in your inventory and the shop. People change these to read the shop faster, not only to look different.

The D2PFX catalog has 11 mods in this category. Each changes what you see on your own screen; everyone else sees their own game.

Installing any of these

Open Dota 2 Mod Manager, find the hero, press Install. The app puts the file in a free pak slot in the folder your game mounts, tells you when two mods carry the same file, and puts everything back after a Dota patch. The full guide, or the manual route if you would rather do it yourself.
