Title says it all. We should be able to click on the Ultimate Reward for the week and preview what it looks like
You can preview it by going to the relevant customisation screen, e.g. Yoroi core - armor coating, you will find it there (says unlock condition is to complete the capstone challenge that week).
I agree it would be useful for 343i to add a preview feature to the capstone challenge in the challenge screen though - it would be more convenient.
Yes please, it’s actually kinda obvious, so a little annoying that this isn’t in there. Just one of those (little) things that makes the game feel unfinished.
