Multiverse Tower Defense Undertale Crates

Undertale Crates are event loot boxes tied to the July 2026 Undertale universe expansion. Codes UNDERTALE (1 crate) and 2K_LIKES_UNDERTALE (3 crates) provide free entry after five wins.

Crate pools skew toward Undertale-themed units and materials unavailable in standard banners. Open during Undertale event windows when luck multipliers stack with Admin Abuse schedules on current events.

Save crates if an event extension is announced on The ROBO Studio Discord — expired event crates sometimes convert to standard pools. Track unit outcomes on units hub before selling duplicates.
