Inferno Pools is a four-player map created by Blizzard for the 2015 Season 1 ladder play.
Official Map Description
We wanted to include at least one big macro map this season and Inferno Pools is that map. Even though rush distances are quite far away, defending the third base on this map will be more challenging than other macro maps we’ve tried so far. There are some unique choices of grabbing the high yield base as the third or taking the island expansion depending on where players spawn on this 4 player map. Overall, scouting and watching for when enemies are coming will be important in order to be able to macro well on this map. 
- Two Xel'Naga Towers in the middle of the map.
- Two island expansions.
