Petroglyph TMs Deadscape; Lays Off More Staff?

Las Vegas-based developer Petroglyph has registered a service mark and a Trademark for Deadscape, which covers "Video game software; computer game software and instruction manuals sold therewith; electronic game programs; downloadable computer game software via a global computer network and wireless devices." We were tipped to this by a source familiar with the company who also tells us Petroglyph has suffered another round of layoffs following cuts last December, and their unconfirmed estimate is that the company currently only has about 20% of the workforce they had before End of Nations development was taken in-house by Trion.
