Gears of War development 'previews'
Below is a collection of thumbnails that were generated for Epic Games’ Gears of War, which were packaged with the game, and preview several different levels that were produced during the development of the game.
It should be obvious why these are interesting in a lot of respects, especially as they show a lot of content that didn’t make the final cut. Each of these previews appear to have been generated either for levels that were produced purely for testing mechanics of the game but as well as levels that were used to lay out prefabricated areas.
