This mod produces up to 1000 new science packs with random recipes. The technology unlock for each science requires 100 each of the previous sciences. The research for the first new science pack requires 100 each of the 7 vanilla sciences, including space science. The research for the second science pack requires 100 each of the 7 vanilla sciences and 100 of science pack 1.

The production recipes for the science packs are randomized from vanilla ingredients. Ingredients judged to be too easy or too hard have been excluded.

There are five mod settings: how many packs to generate, the first medium recipe, the first hard recipe, the seed for randomization, and the number of subs per tech unlock. The last setting affects the text flavor for technologies, indicating the point at which Anti should add the research to the list of goals.

The science packs are described as "sub science" because this mod is designed for the Sept 2021 subevent on AntiElitz's Twitch channel. Taking place during Twitch's SUBtember promo, the initial plan is to unlock a new science pack for every X number of subs.
