Submission 531x4t

The details of how to submit entries will be announced later.

Teams should follow the #osu-locus channel in the osu! Discord server for updates.

Nexus 692g2e

We cannot expect every composer and graphic designer who is interested in participating to be familiar with navigating the osu! community, so the Nexus was created as a system to help those who are looking to form or viable teams.

• The Nexus is a website that will allow s to self .
• Potential participants who are looking to form a team may browse the Nexus to someone who they feel is suitable. We expect the majority of interactions to be composers seeking mappers.
• Once a team has been ed, the team member's bios will be updated to indicate that they are no longer available.

The Nexus is not a compulsory process. It is designed as both a system as well as an additional avenue to help individuals form teams. Participants are welcome to form teams through their own methods as well, but they must still their team if they intend to participate.

The Nexus is available on the Mappers' Guild website.

Voting system 5p4063

A form of community voting was chosen to determine the ranking of the submissions, as it best reflects the osu! community spirit. To combat bandwagoning, a unique elo voting system was developed:

• Voting will only be open to osu! s that are at least 6 months old.
• All valid submitted entries will be checked to ensure they are entirely anonymised.
• Voters will be assigned 5 random entries. They will be prompted to sort the entries under the following judging criteria:

  • Song Quality
  • Beatmap Quality
  • Visual Presentation
• Voters must submit a score on every entry before they are able to vote. They will be expected to evaluate the entries across a single difficulty of their choice (e.g. Normal).

  • If an entry is missing a specific difficulty or does not have any visual design elements, it automatically scores last place under their respective judging criteria.
• All votes will be treated as comparisons and fed into an elo system of sorts to determine the overall ranking of all entries.

  • The process is similar to a round-robin tournament where every player is matched against each other multiple times, except the match outcomes are decided by the voters, essentially taken as "wins" or "losses" and fed into an elo-rating system.
  • This is, in spirit, similar to ranking systems used by games like chess or League of Legends, and was constructed to make the voting more accessible to the general community (by not having to go through every single entry to participate in voting), and to help prevent bandwagoning.

Teasers l5m63

Teaser #1 and #2 are optional submissions. ed teams are allowed to freely submit a 5–10 second video clip showcasing their work. These clips will be stitched together to form a "trailer" that will be featured on osu!'s social media.

The osu! team reserves the right to deny any clip if deemed unsuitable for the event.

General enquiries 5d6g2a

A Discord channel (#osu-locus) will be created on the osu! server. Announcements will be posted there — it will be up to teams to ensure they are caught up with the latest updates, though we will endeavour to inform ed teams of any updates.
