The migration of IL runs from Red Ball Category Extensions has been completed. ILs are now hosted on the Level leaderboard of each individual game in the Red Ball series. The RBCE IL board will remain up for a few days until everything has been archived, but no not submit any runs to it; submit IL runs to their new homes instead! Thanks to this migration process, the following IL categories have been able to be added:

Red Ball 3 - 100%
Red Ball 4 Vol.1 - Low%
Red Ball 4 Vol.1/2/3 - Any% Glitchless - Restricted Speed
Red Ball 4 Vol.1/2/3 - Gold Medal - Restricted Speed

*Restricted speed means that speed can be garnered from previous levels, but it must be done so in the context of that category. Resetting in a previous level refreshes that state, meaning that it only needs to be maintained after that reset.

Happy IL speedrunning!
