The first community race held on Metroid Construction. Z-Factor 1.3 was the initial test run for community races, and it turned out alright. These races are designed for being fun, and showcasing random hacks and games of the Metroid series.
The Metroid Construction community race of Super Metroid: Legacy! More people joined in this one, and it had a lot of testing and practicing this time! These community races are clearly growing into a thing.
