Sonic Frontiers

All Cyber Space areas have an S rank time that needs to be met in order to obtain an Emerald Vault Key. The times vary between areas, but are not too difficult to meet. Many of the levels feature lenient times to do this, so you may get this naturally as you play through the story. If not, areas can be replayed by pressing  at the completion screen, so you can try as many times as you would like. By replaying areas, you will become familiar with faster paths and routes that will allow you to meet the S rank time. Simply get Rank S once on any Cyber Space area to obtain this trophy.
