The screen captures you see show the kind of rooms and levels that are possible. These rooms were rendered in real-time with the A7 engine, and only the simplest geometry was used, no fancy lighting or shaders. You get everything you see used to create these environments plus more.
There are 53 textures in .bmp and .tga format depending on if they have an alpha channel. Most are 1024 x 1024, but some do vary in size, some are skinnier and a few are smaller for details and trim.
There are also 9 detail sprites that have alpha transparency layer which allows them to be placed over the other textures. These images are generally smaller in size and can be used to add detail to your creations. Some of these include a blood stain, a candle, a beam of light, and a pair of shackles.
Still not convinced? Download the preview .zip. It has higher quality and higher resolution versions of the renders shown here. Also the Full Res Sample.zip shows a couple textures in full resolution. Don't go by the compression uses on this site.
These textures may not be resold as a texture pack or part of a texture pack or given away for free, even if they have been modified.
These textures may be used royalty free for the creation of personal or commercial applications including but not limited to, games, models, cover art, and levels.
The end product to be sold must represent a reasonable amount of work; for example, a simple flat plane with the texture on it may not be sold as a 'Cathedral Wall'. On the other hand, a modeled castle or building, inside or out, may be sold. This requirement is to prevent the sale of these textures through a technicality which is unfortunately common.
Great for games!
