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.
- 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.
- 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.
- 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.
- 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.

Start raid preparation with a balanced roster and placements that maximize time in range. These are general tower defense fundamentals; a tested Act 3 lineup, wave order and encounter-specific strategy are not yet confirmed here.
Prepare Your Damage Coverage
Bring focused damage and area clearing, then look for positions that cover more of the path. Treat this as preparation rather than a verified Act 3 clear plan.

Summoned characters form your defense. Understanding their roles helps you build a useful team before chasing rankings. A complete named roster and individual unit statistics are not confirmed here.
Main Damage Dealers
Build around a dependable damage unit and give it enough path coverage to contribute consistently. Consider rerolls once it has stayed in your lineup across several sessions.
Area Clearing and Support
Area-clearing units help handle groups, while support provides another roster role to consider. Check each character's actual abilities when deciding how it fits your team.

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.
