Before Your First Waves

Get Started in the game

How the game Plays

The game is a tower defense game based on Undertale. The game X progression covered here takes place on Roblox: summon character units, position them along enemy paths, and survive successive waves. Main damage dealers, area-clearing units and support give your roster different ways to handle pressure. Placement determines how long enemies stay within reach, while Soul and Trait rerolls offer further progression once you have units worth keeping.

Undertale Adventures Beginner Guide

Your opening priorities are straightforward: check available codes, summon enough units to build a defense, learn useful placements, and save serious reroll investment for characters you keep using.

  1. 1Check the lobby Codes buttonLook on the right side of the lobby screen. Reported code rewards include Souls and Trait Rerolls, but check each code's current status before counting on its rewards.
  2. 2Summon a usable rosterStart learning with the units you pull. Combine a main damage dealer with area clearing rather than waiting for a perfect lineup before playing.
  3. 3Make the path work for youPlace damage units near bends or stretches that keep enemies within range longer. Watch where enemies escape to identify gaps in your defense.
  4. 4Reroll units that earn their placeA character you still use across several sessions is a better investment than one you replace immediately. Build a dependable roster before spending heavily on Soul and Trait rerolls.

Undertale Adventures Character Tier List

Compare units by their battlefield role, useful coverage and performance in the content you are attempting. Named character rankings are not confirmed here; these tier descriptions explain the comparison framework without assigning unsupported placements.

S TierLeading choices with demonstrated performance in the relevant mode. No characters are assigned this rank without supporting comparisons.
A TierStrong choices that contribute reliably when their role fits the lineup. Placement and investment should be considered alongside the rank.
B TierSituational choices that may fill a missing damage, area-clearing or support role. Their usefulness depends on the rest of your roster.
C TierLower-priority investments when stronger alternatives fill the same role. A unit that helps your current defense can still be useful while you build your roster.

Undertale Adventures Player Questions

Quick answers about the first-session decisions that shape your roster, placements and resource spending.

  • When should I start rerolling?

    Once you have a unit that remains useful across several sessions. Investing heavily in a character you immediately replace wastes resources you could save for a lasting pick.

  • Why do enemies keep getting through?

    Check how long enemies stay inside your units' range and whether your roster can handle groups as well as individual targets. Adjust the weak point you observe during the wave.

Undertale Adventures FAQ

Can I read this game wiki for free?

Yes. The guides and reference pages are free to read.

Are any working code strings confirmed here?

No exact code strings are confirmed on this homepage. An October 20, 2026 guide reports Souls and Trait Reroll rewards, but that report does not establish which codes still redeem.

Is this an official the game website?

No. This is an independent fan wiki with no affiliation, endorsement or sponsorship from the game's developer or publisher.

Where do I get Bravery?

Bravery's location, acquisition requirements and drop rate are not confirmed in the available references. The item page identifies those gaps rather than offering an unsupported farming route.

Does this wiki cover the game X?

Yes. The Roblox summoning, placement, code redemption and reroll guidance here covers the game X. Advice about the original Undertale RPG's combat and endings does not establish mechanics for this tower defense game.

What information helps correct a guide?

Include the game version, unit or item involved, and steps that reproduce what you observed. For a raid strategy, record the lineup, upgrades and wave where the result changes.
