A Virus Named Tom developer Misfits Attic is letting players decorate the titular virus with some holiday-themed items, but they'll need to do a bit of work to get the Winter Wonderland pack's free content.

Misfits Attic has set up a scavenger hunt of sorts, with clues to in-game achievements that, when attained, will unlock the decorations for Tom. A new clue will show up each day, for those who need the assistance.

A Virus Named Tom, an indie puzzle action title, launched in August on Windows PC. Check out screenshots of the DLC above, and a trailer for it below.
