An Umamusume character joins your race in Megabonk: select her, watch her run, and unleash her unique ability.
An Umamusume: Pretty Derby girl joins your Megabonk run as your partner.
Choose your partner. Right after you pick your character and map, a partner menu in Megabonk's opens: every girl downloaded in your own copy of Umamusume, with her portrait, her 3D model idling in home-screen poses (drag to turn her), her class, her skill and her stats.
She fights beside you. Her real model, outfit, tail, hair physics and animations are read from your Umamusume files while you play. She roams around you on her own, lunges at the nearest enemy and kicks it, and grows stronger every level. Her Umamusume stats matter: Speed (how fast she moves), Stamina (how long her skill lasts), Power (damage), Guts (how often she kicks), Wit (how far she sees).
Unique skills. Her hits fill the bar under her feet; when it glows, press G. 17 girls have a skill of their own built from Megabonk's effects, weapons and power-ups. The other girls appear as silhouettes and use a preset ability (they're still being worked on)
Needs: Megabonk and Umamusume: Pretty Derby (opened at least once so it has downloaded its character data). Melty installs BepInEx for you. Nothing from either game is in this download.
