As part of the first update, there's bug fixes and improvements.
Bug Fixes:
A bug causing players losing all their items on death. This is fixed.
A bug causing players being able to hit each other. This is fixed.
A bug letting players push others while sliding. This is fixed.
New Stuff:
Added a new button at the end of the map to start over.
Added Special Thanks credits.
Additional Notes:
Fortnite has a bug that doesn't let you walk on walls to climb up tall walls sometimes. The button you can find through the deathrun will help you to skip those parts and keep playing.
Found any other bug besides the one I've fixed? Report them on my Discord server.
