Over the last couple of months, many of you have been asking questions about privacy, the EULA, and how Take-Two (T2) collects personal data and other information from KSP players. We hope this update provides some clarity for the community.

Kerbal Space Program runs on the Unity engine and uses Unity Analytics on PC. Unity Analytics collects gameplay data and certain personal data from players (IP address and device ID). The collected gameplay data includes data on modes, missions, and other usage stats that help us figure out where we can improve the gameplay experience, decide what sort of content to include, and make changes for future updates. For example, we might rebalance missions if we see a low completion rate and think it is too difficult. We learned that players weren’t playing many community-created Mission Builder missions, so we added mission sharing via the Steam Workshop. The personal data collected by Unity is anonymized before the gameplay data is sent to T2.

Unity Analytics directly collects some personal data on KSP, which you can read about here. We are releasing a version 1.4.5 update that, among other updates to the game, allows players to opt-out of Unity’s collection of personal data. The opt-out tool will be displayed at the main menu during the first time you play 1.4.5 and can be displayed again using a toggle in the settings menu. KSP: Enhanced Edition on console does not currently use Unity Analytics.

For a period of time, T2 used Red Shell in KSP to analyze the effectiveness of marketing campaigns. To do this, Red Shell collected IP addresses, device ID, and an in-game user ID to help T2 understand whether or where a KSP player saw an online ad for KSP. The personal data Red Shell collected was one-way hashed before sending the aggregated campaign analysis to T2 (you can find out more from Red Shell here). The Red Shell SDK was implemented in version 1.4 of KSP and, based on community feedback, removed in version 1.4.4. T2 instructed Red Shell to destroy all KSP data Red Shell has collected. Even if you are using a KSP version that still contains Red Shell, no data is being captured by Red Shell’s servers.

As some of you have correctly pointed out, KSP’s EULA is a blanket EULA for all T2 games. After T2 acquired KSP, T2 transitioned KSP to T2’s standard terms including its EULA, privacy policy and terms of service. T2’s EULA applies to its broad portfolio of games, covering various genres, platforms, and business models. At this time, T2 continues to collect only limited personal data for KSP—limited to the personal data that players provide directly through purchases from the KSP store and through signing up for the KSP forums and wiki. This is standard practice whenever you make an online store purchase or join an online forum.

We hope the above information provides some clarity about personal data and KSP. The KSP community is the reason why the game is as popular as it is today, and we strive to continue supporting you.

Hello everyone!

Kerbal Space Program 1.4.4 and Making History 1.3 is about to be launched!

This patch includes various improvements and bug fixes for both the base game and the Making History Expansion, as well as language corrections.

Additionally, this patch includes some new Steam features, including the full in-game integration of the Official KSP Steam Workshop hub, the implementation of Cloud Saves on Steam for both game saves and missions and an improved and expanded controller support via the Steam Controller framework. Click here to learn more about these features.

Check out this patch's Changelog for further details here.

Happy launchings!

Patch 1.4.4 is on its way and with it various improvements and fixes such as language corrections, FX improvements, and more! As part of our commitment to continue supporting and improving upon KSP, 1.4.4 will add some cool and previously unavailable Steam functionalities that will enhance the KSP experience to users of this platform.

For starters, we’ll be launching the Official KSP Steam Workshop hub, along with its full in-game integration. Since the conception of the Making History Expansion, we knew that mission-sharing was crucial for its success. Now, with the integration of this platform into the game, we are making it easier for creators and players to share Missions and Crafts without having to mess around with copying folders from other websites and putting them in the KSP folder tree. This feature will allow you to upload your creations to the hub directly from the game, as well as to subscribe to and vote for your favorite missions. Additionally, it gives us the ability to feature missions from the community and drive visibility to these creations. With patch 1.4.4, it will be more straightforward than ever to enjoy all the content made by the players for the players!

This patch also implements Cloud Saves on Steam for both game saves and missions. Once 1.4.4 is released, players will be able to access their save files and mission files from any computer by logging into their respective accounts.

Last but not least for 1.4.4, we’ve improved and expanded the controller support for the game via the Steam Controller framework. With the intention of closing the gap between the mapping found in the consoles’ Cursor Mode and the one currently supported in the PC game, we’ve carefully provided configurations and full support for DualShock 3, DualShock 4, Xbox 360, and Xbox One controllers, and added a new configuration for the Steam Controller and one for HOTAS-like joysticks. We also added a supplementary contextual controller set for EVA situations, in addition to the currently existing ones for the Menus, VAB/SPH commands, Flight Controls, Map, and Docking Mode. Click here to see the new controller layout.

We hope you enjoy these new features. Keep an eye out the patch’s release later this week, and stay tuned for more news and everything Kerbal via our official forums and our various social media channels.

Happy launchings!
