Type Notes
Free-to-play The entire game is free to download and play, only requiring a free Steam account.
Subscription Dota Plus is a premium monthly paid service that offers real-time progression and strategy suggestions, additional ways to earn cosmetic items, and detailed player statistics along with other out-of-game bonuses.[3]


Type Notes
Cosmetic Many items from the heroes to the map itself can be customized with skins that can be earned through gameplay, or pourched with real-world money from the Steam Market or directly in the game itself.
Free-to-grind Some cosmetic items are dropped periodically when playing the game.[4]
Infinite spend New cosmetic items are constantly added to the game on a periodic basis.
Loot box Treasure chests can be opened that contain a varying degree of chance to obtain cosmetic items of varying rarity and chance.
Player trading Players can trade items obtained from the game to each other using Steam's trading feature.
Time-limited Some cosmetic items can only be obtained between a specific time period. One example is Declarations of the Divine which is only accessible to The International 2020 Battle Pass owners and "will never be tradeable or purchasable on the marketplace".[5]

Issues fixed

Blurry graphics

Set render quality to highest[14]

Missing health and mana bar

Console command: hud_sf_reload dota_sf_hud_actionpanel[15]

2D sprites and effects displaying over geometry [AMD 7000 series)

Do not override catalyst control center, turning it off or overriding it with programs like "Radeon Pro" will cause graphical issues in Dota due to poor AMD GPU support, re enabling it should fix this issue[citation needed]

Pixelated shadows

Instructions[citation needed]
  1. To make shadows smoother, go to <path-to-game>\dota\cfg\video.txt
  2. change "setting.cpu_level" "0" to "setting.cpu_level" "2".

Game changes microphone gain at launch

Modify configuration file[16]
  1. Go to the configuration file(s) location.
  2. Open config.cfg.
  3. Find the line voice_mixer_volume, it should be near the bottom of the file. If the line doesn't exist you may create it.
  4. Set the value to whatever you prefer your mic volume to be, I set mine to .5 which translates to 50% gain.


Removing the line does not work.
This will set a fixed value, and might not be a solution for people who are using dynamic gain which Windows (or other applications) automatically adjusts.
Disable exclusive control of microphone (Windows)[17]
  1. Right click on the speaker icon located at the tray bar.
  2. Select Recording devices.
  3. Double click on your microphone in the newly opened window.
  4. Go to Advanced and untick Allow applications to take exclusive control of this device.


Most applications ignores this, and many users are reporting that it isn't working.

Rebind number keys to quick cast items

How to rebind your number keys if suddenly they don't work in Dota 2 anymore
  1. Open game console with ` or any key you used to open console.
  2. Write into console bind "1" "dota_item_quick_cast 0" to bind keyboard key 1 to quick cast item 1.


Item 1 is bound to dota_item_quick_cast 0, item 2 is dota_item_quick_cast 1, and so on.
A full list of console commands can be found here
