StarCraft 2 is about to get a hefty update in the form of patch 4.3.0, in which two new maps for its Arcade mode will be introduced. The Arcade maps were put together by prominent members of the StarCraft community, with Blizzard working on the teams behind the scenes. The result is two premium Arcade maps with interesting experiences that, when purchased, allow for a share of their sales to go back to the developers who came up with the concepts in the first place.
The first of the two maps available is ARK Star, from Daniel "Pirate" Altman, who won Blizzard's 2015 Rock the Cabinet contest earlier. ARK Star is a tactical, turn-based RPG that stars the Protoss as its protagonists. Yes, an RPG created entirely within the confines of StarCraft 2. Awesome, right? It'll cost you $4.99 to adventure behind the templar team of Sol Seekers as they search for a mysterious weapon known as the ARK Star to dismantle and destroy it.
Next up is Direct Strike, from community creator Aya, which is the "next evolution" of Desert Strike HotS. It will be free for the near future, but you can pay an optional fee to upgrade to a premium version with cosmetics and additional modes or $4.99. Direct Strike is a tactical exercise where you can build units to send into your staging area and then send out in waves to take down your enemies.
Both of these community-made maps will be available in the coming weeks, and you'll be able to make them yours when patch 4.3.0 hits. Unfortunately, there doesn't seem to be an official release date for the patch right now.
