Undertale Adventures X Hotland Act 6 Genocide: Modes, Regions, and Farm Guide

Why Players Keep Asking About Hotland, Act 6, and Genocide

If you have been grinding the same stage for hours wondering why your soul fragments stopped flowing, the answer usually sits in the mode you picked, not the units you built. In Undertale Adventures X, Hotland, Act 6, and Genocide are three separate levers that change what a run pays out, and mixing them up costs more time than any bad summon. This guide walks through the Undertale Adventures X Hotland Act 6 Genocide question from the ground up: where Hotland sits in the region order, what Act 6 actually throws at you, and how a Genocide path changes the grind. By the end you will know which Undertale Adventures X Hotland Act 6 Genocide setup matches your goal — fast XP, trait materials, or a specific drop.

Undertale Adventures X is a free Roblox tower defense experience from Side Productions. You place Undertale-inspired units, level them up, and layer traits on top of them. The public record for the experience was updated in October 2026, and the region list has grown considerably since the game was created in July 2024. You can find the live experience and its community page through Roblox's official platform.

The Region Order Players Actually Entered

Any Undertale Adventures X Hotland Act 6 Genocide discussion has to start with region order, because Hotland only exists as a farming destination if you have already cleared what came before it. Community documentation tracks regions by the date footage showed them playable, not by developer patch timestamps — an important distinction when you are comparing an old guide to the current build.

Two details stand out. First, Snowdin notes say trait materials became harder to obtain after that update and stopped dropping from ordinary stage clears — which is exactly why late-game players hunt specific modes instead of replaying story stages. Second, Muffet and the Mettaton forms are still listed in October 2026 role tables, so at least part of the old Hotland lineup survived into the current build.

Act 6, Genocide, and the "All Acts Pay the Same" Myth

One of the most repeated lines in older guides is that every act pays the same XP and souls. That was accurate in a narrow window: an August 3, 2024 prep video said every act at that time paid equally, which made Act 1 Neutral the fastest XP clear and a later Genocide act the better drop farm. It stopped being reliable almost immediately afterward.

By the time Waterfall arrived in September 2024, the economy had already shifted. Act 6 footage published on September 25, 2024 shows flying enemies opening the wave and longer waves overall than earlier acts. If you are planning an Undertale Adventures X Hotland Act 6 Genocide run today, plan for a longer sitting than an Act 1 clear, and bring answers for air units in the opening seconds of each wave.

Hotland Roster: What the Old Banner Listed

The most detailed Hotland roster available comes from a June 11, 2025 unofficial changelog, which listed a Hotlands banner with nine named units. Community reports have not verified that list against the October 2026 build, so treat it as a historical snapshot rather than a live banner.

If you are chasing a specific Hotland unit, open the live banner before spending anything. Player experience says the safest habit is to screenshot your current banner, then compare it against whatever guide you are reading before you commit resources.

Why Hotland Became the Kill-Grind Spot

Hotland's reputation comes from player questions rather than patch notes: through 2025, "where do I grind kills" threads consistently pointed at Hotland and the Core beside it. The pair works because both sit late in the region order, so enemies there are worth more progress per run than Ruins or Snowdin clears.

A simple loop for the Undertale Adventures X Hotland Act 6 Genocide grind:

• Clear the Act 6 opening with splash or multi-target units, since flying enemies arrive first.
• Bank souls and XP on a repeatable stage rather than a one-time story clear.
• Move to Hotland or the Core once your units can survive the longer waves.
• Spend trait rerolls in batches rather than one at a time — the trait pool has 12 entries.

Modes Beyond the Campaign

Not every Undertale Adventures X Hotland Act 6 Genocide goal belongs in the campaign. Several side modes have historically paid better for specific materials, and knowing which one to queue is half the battle.

The short version: Gauntlet is your currency faucet, raids are your skin source, and the campaign is your XP and soul faucet. Running the right mode beats running more hours.

Picking the Right Act for Your Goal

Before you commit to an Undertale Adventures X Hotland Act 6 Genocide grind, match the mode to the outcome you actually want.

Two more habits worth keeping. Read the percentage in your own Traits menu before spending a large stack of rerolls — the rate table in circulation matches an August 2024 odds screen for Royal Guard Soul at 15%, and reroll odds are exactly the kind of thing that quietly changes. And keep an eye on the code field: the HOTLANDS2025 code that named the region has already expired, so treat any code list older than a few months as history rather than gospel.

FAQ

Is Undertale Adventures X free to play? Yes. It is a free Roblox tower defense experience by Side Productions. You defend a base with Undertale-inspired units, level those units, and strengthen them with traits. There is no paid entry requirement to start.

What is the difference between Act 6 and Genocide in Undertale Adventures X? Act 6 is a campaign act — September 2024 footage shows longer waves with flying enemies up front. Genocide is a run type, and a Genocide act is traditionally the drop farm rather than the fast XP clear. Most players combine the two when planning an Undertale Adventures X Hotland Act 6 Genocide session.

Where should I grind kills in Undertale Adventures X? Community reports point to Hotland and the Core, the areas players named next to each other when asking where to farm kills in 2025. Both sit late in the region order, so each run is worth more than an early Ruins or Snowdin clear.

Do the old trait rates still apply? Partly. Trait rerolls assign one of 12 listed traits, and the circulating rate table matches an August 2024 odds screen for Royal Guard Soul at 15%. Check your own Traits menu before committing a large stack of rerolls, because the table you found may be older than the build you are playing.
