This is a sub-page of Driveclub.
global.rpk is the real gold in the game files, as it has a boatload unused and placeholder graphics.
A checker map.
A dialog for "Cupcake Beta Test". Cupcake is the codename of Driveclub.
This watermark was used in the E3 2014 demo, but was leftover in the final game.
4 images of varying widths, while 128 is always the height.
A small image of a MotorStorm game, used as a placeholder.
And to finish it off in this resource pack, many, many more unused watermarks.
newui/art/placeholder.rpk includes way, way more though.
2 lines and a bunch of dots.
A placeholder image for an announcement about the online servers being under maintenance.
A placeholder image for a default announcement.
Could be a leftover from MotorStorm. No explosions ever happen in Driveclub, so this goes unused.
In haboob.rpk, the texture atlas contains multiple test textures.
In patch 1.28's newui\art\osd.rpk, there's an alternate version of the speedometer that's never used.
This loading screen for the Tamil Nadu Invitational race went unused after the first race you start in a new save was replaced with the Welcome to Driveclub race.
In patch 1.28's osd.rpk, there are 2 crudely drawn stars.
