1v1 map pool additions:

This map features close rush distances in most start locations, and the natural expansion is fairly easy to access, due to the rock guarding a part of the choke point. This means that the map won’t be strictly about the rush, even though it’s a rush map.

Kerrigan’s Wrath is a symmetric map with no spawn point that is favored over the others. Without breaking the two rocks, this map is very straightforward to play, but when the paths blocked by rocks are opened up, you'd better take notice!

Unlike Kerrigan’s Wrath, Shifted Sky will have varying gameplay depending on where you and your opponent spawn. You’ll want to bring multiple strategies to this map, and adjust your game depending on your and your opponent’s start locations. This map also features an extremely large number of different attack paths, some of which can be opened up by breaking rocks.

This is the macro map for Season 3. Early on, it will be possible to easily take two expansions. This, along with the long rush distances in all start locations, will most likely encourage players to go for a mid- or late-game strategy, rather than a quick, rush-based strategy.
2v2 map pool additions

In 2v2, we’re trying to go with mostly maps where you and your ally have a shared choke point to defend. At higher levels of 2v2, there are clearly team compositions that are stronger than others on open maps. We’re hoping to address this balance issue through map layout, since this is only a 2v2-specific issue.
3v3 and 4v4 map additions
3v3 maps
4v4 maps

Looking at the statistics, we’re seeing that the higher level players rarely play these formats. Therefore, we’ve decided to go with a bit more of a casual-player-friendly selection of formats. We want to provide a good mix of fortress style maps, as well as rush maps, to cater to the broad player base here. Our goal for these two formats is for players to be able to enjoy variety in the gameplay, rather than trying to provide an eSports level of game balance.
