Overview of DLC Released on September 23, 2025

◆RPG Developer Bakin Vibrato HERO PIXEL PACK Vol.2

This DLC is a collection of high-resolution pixel art character assets, newly created by pixel art artist Vibrato, based on the four characters included in RPG Developer Bakin's standard assets: "Warrior A", "Warrior B", "Elf A", and "Elf B".

Compared to the 40 x 40 pixels per frame of the standard assets, this collection is produced at about four times the resolution. The details and personalities of each character are expressed more finely and attractively. 

It also includes 14 exclusive actions and poses that match the characteristics of each character. This enables dynamic movement and rich emotional expression, and greatly expands the range of in-game production.

◆RPG Developer Bakin PixelScapes Modern Suburban Pack

PixelScapes Modern Suburban Pack is a pixel-art style 3D model set for recreating cozy, modern suburban neighborhoods.

It includes a wide variety of friendly and inviting suburban elements such as houses, shops, playgrounds (with swings and slides), and school buses—perfect for games set in modern-day life, mysteries, school settings, and more.
