Over the last few years, many popular gacha and mobile games have found a pretty consistent path toward enticing users both new and current: crossover events. Ranging from simple costumes to full character inclusions and themed missions, these events are generally a treat for all involved, even if you arent already tuned into both involved IPs. For instance, Honkai: Star Rail, the only gacha game I like, has managed to secure two separate crossover events with Fate/Stay Night, culminating in multiple fully-voiced characters, new cinematic missions, and even permanent game modes. Archer even ended up being a top-tier Hunt unit.
