Along with a major update (update 3) to all rules.
Please note that I've moved a number of rules from other supplements to (A)-Base (D)-Landing. As a result, I'm making it available for the next 3 months on a pay want you want model (minimum $1), to allow everyone to have a chance to get these rules if they've purchased the game previously before it becomes a full price supplement.
You can access it at https://half-apress.itch.io/a-base-d-landing along with a contents page.
