**Fellswap X** is an AU inspired by the early concepts of Fellswap Gold, but while using the Fellswap idea as the basis for the setup, it is more than simply a fusion of the 2. The AU focuses around the cold war that is happening between monsters and humans, and the conflict and turmoil occurring in the Underground.

In the AU, magical attacks as seen in Undertale do exist, but most monsters don't use them for attacks. Instead they power weapons with the magic of the user and use that to fire actual ammunition, like bullets. This method of attack tends to be far more deadly, preventing the victim from healing their wounds with magical items and leaving them with scars and deformities, if they don't die. However, some monsters disagree with this method.
