The description still introduces the Release as a tower defense game where you defend with Undertale units, level them, and strengthen them with traits. No patch notes were posted on the listing, so this entry does not claim new units, codes, or balance changes. Recheck the Codes button and the trait percents after you join.

How do codes work?

Do trait rates still match the old table?

Trait rerolls assign one of 12 listed traits. The rate table matches an August 2024 odds screen for Royal Guard Soul at 15%, and a November 29, 2024 video described the Perseverance buff the table now shows. Read the percent in your own Traits menu before you spend a large stack of rerolls.
