Notes
No depot information available for this app.
A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

Added:Since there is no standard tutorial, Red Alerts will now flash to draw your attention to them. The flashing will stop once clicked. The 'Basics' tab in the Data Center also includes this info. Changed:You can still click the system recharge toggle, but now you can also turn it on and off using the W key or UP arrow key (mentions this in its hover prompt).

How checkpoints use to work: Say you survive day 100 and 101, then you get overrun on day 102. The checkpoint system would have had you begin on day 100 wave 1. How checkpoints work now: Say you survive day 100 and 101, then you get overrun on day 102. The checkpoint system will now have you begin on day 102 wave 1.

Changes: The "Next Day" button will now flash when wave 30 is reached. To help direct a new player to learn how systems work, I reworded the greeting prompt. Instructions to check the Data Center before continuing are a lot clearer now.
