Generals!

Today marks the last pre-summer patch with fixes and tweaks to Thunder At Our Gates. After this the team will have limited presence in the office for the summer period.

We know that this patch does not hit all the sought after balance changes but for that we’d like to refer to you a new Open Beta that we will be running over summer that will address some of those issues.

For now, be fully immersed in the rumble in the jungle with the summer heat seeping through your windows. See you all after summer!

**ROLLBACK**
For this release we’ve added the option to roll back to our recent Patch 1.19.1. This is useful for players that have saved games that they would like to finish, before moving onto 1.19.2.

-  Right click the game in Steam

-  Go to Properties, then Game Versions & Betas

-  Select 1.19.1

-  Default Public Version will use the latest public build, in this case 1.19.2
