Underground sidescroller background
Playing around with a sidescroller background from the "Superpowers" set posted by MedicineStorm, I made some variations on it, and here they are.
The first one is almost unaltered; apart from the palette, the main difference is that it tiles slightly better in the vertical direction than the original does.
As you can see in the mock-up, the colour palette here is chosen to work with the 16 colour version of the Space Merc Redux tileset, using only one of the free palette entries.
