Warning:

• The {{{game}}} parameter is inconsistent with the name defined by the {{SoHL}} template. This can most likely be fixed by setting the value of the {{{game}}} parameter to Spirit of Half-Life.
  If a parameter is consistent but you're still seeing this warning, it may be an issue with the template itself. Please discuss it on the template's talk page.

It is a projected decal.
