The player takes on the role of Baldur (voiced by Crispin Freeman), one of the Aesir.

In Too Human, the Norse gods are cybernetically enhanced humans. Baldur, son of Odin, is one of these gods and it is his duty to protect the human race from an onslaught of an advancing machine presence determined to eradicate all human life.

The story chronicles the ongoing struggle between cybernetic Norse gods, the invading machine presence and mortal men, it features many Norse gods and characters from Norse mythology including Thor,Loki, Odin, Heimdall, Freyja, Hel, and Mimir. Yggdrasil: the tree of life acts as a gateway to an alternate world known as Cyberspace that is accessed through the advanced technology of the gods.

The human gods are using cybernetic implants to supplement their own abilities, thus becoming more machine like. Conversely, the advancing machine army is harvesting human blood and limbs in an attempt to become more human.

Baldur, the main character is viewed by the other Norse gods as being insufficiently enhanced, thus "too human".
