Wrote a song for XCOM 2. Also, it has aliens - therefore, theremin.
Lyrics:
Verse 1:
We used to look
To the skies for offerings
Now we know the stars
Bring naught but suffering
But stand fast
From the silence, we'll emerge
Swift and victorious
We'll combat this scourge
We, heroes of the Earth
Chorus:
With science and the will to life
The apex, of the human mind
We'll fight forever day and night
Heroes of the Earth unite
Verse 2:
Their genetic makeup
They think will fool us
Xenoscience cannot hide
Their inborn malice
Like old gods they offer
Gifts from up on high
But our prayer for freedom
They cannot satisfy
For we, are avengers of the Earth
Chorus:
With science and the will to life
The apex of the human mind
We'll fight forever day and night
Heroes of the Earth unite
