Mission Model Build Instructions
Every English building instruction PDF, matched to its mission and bag numbers.
← Back to BIOGLOW Season ResourcesMissions & Bags
Sort the LEGO bags from the Challenge Set by their printed number, then open the matching PDF. Open one set of bags at a time so the elements don’t get mixed up. Build the models exactly as shown — practicing with an incorrectly built model will hurt your gameplay.
