The Spirit Lifter: Steerage & First Class (unofficial name) Often called "Spirit Lifter" and is a song performed by Deep Cut.

Description
The Spirit Lifter: Steerage & First Class is an energetic pop song. The song starts with an instrumental intro, then a verse sung by both Shiver and Frye. The second verse is two solo parts, first by Frye, followed by Shiver. The first verse is then repeated. Afterwards, an instrumental bridge is played before looping back to the intro.

This song is played during two missions in Alterna Space Center of the Return of the Mammalians single player campaign in, first during The Spirit Lifter: Steerage, then immediately followed by The Spirit Lifter: First Class. While the same song is played continuously throughout these two missions, it is worth noting that different percussion instruments are used separately for these missions. The transition to the different instrumentals happens after the player lands onto the latter mission.

Like in many other missions, when the player has been spotted by enemies, an additional percussion track is layered on top of the music.
