Few things are as harsh as a Kaldir blizzard. Resources are hard to come by, and the winds freeze everything they touch. Destroy Amon’s shuttles, and try to keep warm.
Blizzard - Storm clouds move across the map, damaging and freezing player units in their path.
Slim Pickings - Player worker units gather resources at a reduced rate, but resource pickups spawn throughout the map.

[Reddit Post Link]Notes:
- The Blizzard clouds move from left to right across the map. Even touching the edge of a cloud will slow down your units considerably.
- The Blizzards do not pass through players’ expansions.
- Workers gather 1 resource per trip on Brutal difficulty. It is still worth it to expand, but you need to take your expansion early for it to pay back its cost and be worthwhile.
- Using patrol on single units/workers is a good way of seeing the resource pickups. They still appear through the fog of war so you can return to them later. Don’t take too long, though, as the pickups despawn at some point.
- This mutation in general is anti-economy and anti-small units. Therefore, commanders with strong hero units will do extremely well here.
