Dota 2 was released through which Valve digital platform?

The story behind the answer

Dota 2 was released through which Valve digital platform? Dota 2 was released through Valve’s digital distribution platform, Steam.

Valve began developing Dota 2 in 2009 after hiring IceFrog, the lead designer of Defense of the Ancients. The standalone game entered a Windows-only open beta in 2011 and reached its full release in July 2013. Its launch distribution for Windows, Linux, and OS X was handled through Steam, tying the game to Valve’s established PC gaming ecosystem.

Steam provided more than a download button. Dota 2 used Steam for account access, updates, social features, matchmaking-related services, cloud storage for settings, and community functions. The platform also helped Valve support the game as a long-running service rather than as a one-time boxed release.

A common mix-up is confusing Steam with the Source engine. Source was the technology used to build the game, while Steam was the digital storefront and distribution platform. Dota 2 is free-to-play, so players can install and play its core experience without purchasing the game upfront.
