Update v20180926:

New Feature: Challenges
Challenges are a new game mode where you have to accomplish a specific objective within a time limit. Mission parameters, game rules and colony coordinates are predetermined and unique for each challenge. A total of 24 challenges are now available.

Self-sufficient Rovers
Rovers no longer have batteries and there’s no need to recharge roves from Power cables. We reevaluated this mechanic and decided that the amount of micromanagement it required was more tedious than actually presenting a meaningful challenge. We are removing it as part of our initiative to reduce the unnecessary micromanagement in the game and allow the player to focus on more important tasks.

Rover Command AI tech now enables automated mode for Explorers and Transports.

Changes to Concrete Deposits
We have reworked the Concrete Extractor to work more in line with other extractors. Concrete Extractors have to be placed in the vicinity of the concrete deposit marker and no longer take into account the specific patch of terrain they cover. This way concrete deposits can be fully exploited even with a single extractor.

Changes to Maps
Due to the changes in concrete deposits, as well as other fixes to the random map generator, all maps have been generated again and will look different than previous versions. Environmental variety of maps has been improved.

Changes to Research
The randomization of research (both order of techs in the research tree and breakthroughs discovered from anomalies) is now tied to the random seed of the individual map. This means that techs are always the same on the same map but different between different maps. This change allows players to compete for score on even terms on the same map coordinates and to have the same experience with techs when attempting Challenges.

Changes to Messages
Popup messages will now arrive first as blinking notifications, which will pop up after some time has passed. This way popups will not interrupt your current actions like placing or managing buildings. Some important messages will still pop up without a notification.

Controller Support for the Infobar
"Resource Overview" buttons are removed from the HUD for both mouse and controller interfaces. The Infobar can now be navigated using controller. Rollover highlights have been added to the Infobar in the controller version of the UI.
