November 2, 2026: I had a look for new Undertale Adventures codes, but those from last week are still the most recent so make sure you've redeemed them!
These Undertale Adventures X codes can help boost your Soul and reroll stock allowing you to summon new units or upgrade your existing ones. Soul Fragments can be combined into Souls, which are required to summon units, while you'll need to head to the upgrades area to use rerolls and buff your team's stats.
This Undertale-inspired Roblox game is a tower defense game, so your units are your most important asset, and making sure that your squad is the best it can be will prevent you having to replay chapters by effortlessly passing them all first time. So, to unlock more recognizable Undertale characters for your team, here are the latest Undertale Adventures X codes.
If you're after some more general rewards that can be used in all of your experiences, then we've got the current Roblox promo codes covered too.
