Valve Software’s Dota 2 has received the first act of its co-op campaign. Act 1 is known as “The Sands of Fate” and is part of the Siltbreaker storyline. This is Dota 2’s first non-PvP campaign and supports up to four players overall.

Siltbreaker is available for those who pick up this year’s The International Battle Pass for $10. Other items have been added to further sweeten the deal and though, the Level 75 Battle Pass is also on sale, everyone who owns the base Battle Pass can play the co-op campaign.

If you want to level up the Battle Pass then playing Siltbreaker is a good idea since Battle Points can be earned from the same. The campaign will also have its own items tied to the quests and can be equipped as you play through.
