Indev (or elopment) was an older test version of Minecraft's Survival mode, which succeeded Survival Test in Classic Mode. Indev received 29 updates after this, gaining a few fundamental features to Minecraft as it went, which are listed below. A few functions that Indev contained are no longer seen in Minecraft today, such as picking out map characteristics, having to save and reload maps and the isometric map viewer. Indev was phased out in favor of Infdev after infinite maps were to be added into the game. As Indev progressed from testing items and blocks to testing the actual survival aspect, these chests were removed. As it progressed, its game play became standardized to that of Minecraft today, however with far fewer features. Indev version 0.31 was put to the public at minecraft.net/indev and available only to people who had purchased the game. On February 23, 2010, Indev received its last update and work on Infdev started, a new mode that would use maps that would have no boundaries and would go on forever. In September 2010, Indev, along with Infdev were removed from the site and cannot be played anymore. The map would then be created and spawn them in an “Indev House".
