The announced bundle included Polychrome ×30, Denny ×12,000, Senior Investigator Log ×3, W-Engine Energy Module ×2, and Bangboo System Widget ×1. Polychrome was limited to the first 300,000 qualifying recipients. Eligible servers were America, Asia, Europe, and TW/HK/MO; the code expired August 14, 2024, at 03:00 PST.
