Which map is set in a Korean mecha factory?

The Overwatch map set in a Korean mecha facility is Busan. The map is located in Busan, South Korea, and one of its three playable areas is MEKA Base, the headquarters of Korea’s Mobile Exo-Force.

Busan is a Control map divided into three distinct sections: Downtown, Sanctuary, and MEKA Base. Downtown presents a busy modern city with transit infrastructure and entertainment venues, while Sanctuary features traditional Korean architecture and a temple-like setting. MEKA Base shifts the mood toward military science fiction, with launch areas, defensive structures, and the team’s combat mechs.

The base belongs to the MEKA squad, Korea’s frontline defense against the giant omnic threat known as the gwishin. D.Va is the squad’s most famous pilot, but the unit includes several other pilots and machines. The map was developed alongside the animated short “Shooting Star,” which focuses on D.Va defending Busan.

The wording can cause a small confusion: the entire map is not a single factory. Busan is the overall map, while MEKA Base is its Korean mecha-centered sub-area. Among the listed answers, however, Busan is the clear canonical choice.
