7. HorrorTale the Game by HTTG Team

Best Undertale Fan Games HorrorTale

The story of HorrorTale unfolds after the Exiled Queen ending, a timeline where Toriel briefly reclaims the throne, only to be banished back to the ruins by the formidable Undyne.

Undyne's authority falls into unimaginable cruelty as a result of a deep-seated desire to exterminate humanity, bringing the Underground to the verge of collapse. Due to a severe lack of food, monsters are forced to do unspeakable things, including eating any unfortunate humans that fall to the ground. Almost everyone is engulfed in madness, and hope is fading.

Aliza, our protagonist, a timid and weak young girl between the ages of 9 and 12, enters the scene. Aliza lacks the strength to fight these huge creatures, unlike the tenacious Undertale heroes. She makes up for her lack of physical strength, though, with a startling cruelty.

She has no link to the original Undertale protagonist, and her voyage into the Underground takes place a long time after the neutral run. Aliza's soul exemplifies both perseverance and fear, which is appropriate given the difficult route she must travel.

One Underfell fan game stands out as a terrifying and fascinating alternate universe (AU) among the enormous sea of Undertale fan games.

In this place, kindness is a rare commodity and fear is the norm.

Frisk, our main character, is a youngster trapped in this terrifying environment. Underfell's Frisk faces a difficult challenge, in contrast to the first Undertale, when nonviolence and friendship prevailed. As they make their way into the perilous depths with the aid of an unexpected companion, Flowey, the wise and helpful flower, they attempt to make friends with folks who would ordinarily have homicidal intentions.

Yet, luck alone won't cut it in this grim and depressing portrayal of the underground. Frisk and Flowey must call upon a powerful quality that is specific to Undertale: resolve. This trait serves as their anchor and motivation in a world where every interaction could end in disaster.
