Indev (or In Development) was the third phase of Minecraft's development cycle and an older test version of Minecraft's Survival mode, which succeeded Survival Test in Classic Mode. Indev was phased out in favor of Infdev after infinite maps were to be added into the game.

Indev was initially released on December 23, 2009 after Notch received requests to let the community try out new features he was implementing. Indev version 0.31 was put to the public at and available only to people who had purchased the game. New features currently contained a more complex and realistic lighting scheme than Classic mode's and support for MD3 mob models, demonstrated by Rana. Indev received 29 updates after this, gaining a few fundamental features to Minecraft as it went, which are listed below. During its lifespan, some updates were devoted mostly for testing new things, like torches or fire. As it progressed, its game play became standardized to that of Minecraft today, however with far fewer features.

Players would play on a limited map with dimensions determined by the shape and size characteristics. Game play was dramatically different from Survival Test and paved the way for future game modes to come. Players now had to use tools and weapons, gather and prepare food differently, utilize crafting and smelting and be wary of the time of day. Like Survival Test however, players still had to save their map to a file on their computer and reload it if they died.

Indev's limited maps soon raised opportunity for a game changing idea. 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. Indev remained available on during Infdev's life and into Alpha mode. In September 2010, Indev, along with Infdev were removed from the site and cannot be played anymore. 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. These were replaced by biomes, automatic map saving, respawning upon death and a new infinite map viewer (which has been removed).

The Indev House[edit]

The Indev House when it was made of moss stone.

The Indev House was a 7 block wide × 7 block long × 4 block tall structure, with a 1×2 hole for players to exit and two torches on the interior. The House would be formed around the player's spawn point when they spawned. When Indev Houses were added, they were made of moss stone (which was unavailable naturally on the map anywhere else) and 4 chests, one filled with TNT, one with a full stack (99 at the time) of every type of block, another with every type of item and one filled with every colour of wool. As Indev progressed from testing items and blocks to testing the actual survival aspect, these chests were removed. Later, the design of the house was changed. The floor was changed to stone and the walls and roof were changed to planks.

Features over Survival Test[edit]

  • You cannot play Indev in the new launcher without your own .jar and .json file.
  • It was possible that features like Indev's finite maps would have returned in the cancelled game mode Zombie Siege.
  • Inside the Beta 1.9 pre-release 6 jar's "title" folder is a file named 'earlyplayers.txt' that contains the account names of the supposed '1000 first paying alpha players' of Minecraft. According to a Reddit post by Jeb, the names were originally going to be displayed in the credits, but the list wasn't 100% accurate, so the idea was scrapped.[1]
  • Indev's terrain.png contained the texture for the Web block, although it would not be added until Minecraft Beta a year later. The colored Wool blocks from Classic mode were also possible to obtain in Indev through hacks or via the item chests in earlier versions.
    • There were textures for a chair block that were removed in Infdev. Any such block still does not exist, suggesting the idea was scrapped or has just been put off for a very long time.
  • If you try to play Indev today, without hacks or a proxy debugger, you may be kicked back to the main menu. On Indev 0.31 you will crash with a java.lang.NullPointerException. This can be caused by some folders or additional jars to be missing, but mostly the fact that the login system was removed.
  • Indev had no gaps in the bedrock layer, neither did Classic, though Infdev and Alpha (Before 1.2.0) had them.
  • In Indev and Infdev, while in the inventory, the player's arm, while in first person view, would slowly sway back and forth. It is possible to move around while this happens. When you do, the arm will flop around randomly as if you were in 3rd-person. If you close the inventory, then the arm will pause in the position it was in while it was flopping around. You can reopen the inventory and it will reset the arm. If you use a crafting table, chest, or furnace, then you will not be able to move, but the arm will still slowly sway back and forth. This does happen in early Alpha, but has been removed and is not currently known if it is intended to return.
  • If you walked out of the map, you would be pushed back into to the level. The further out you went the faster you would be pushed back. This does not happen in 0.31 Indev.
  • If played today, Indev has sound, but Infdev does not. This is because Infdev resources were removed from
  • Indev contained a color pallete image titled "cube_nes.png", which matches the color pallete used for the Nintendo Entertainment System.
  • If you play Indev today, your character will have a completely black skin. This is because Mojang removed support for skins via Indev. You can still become Steve by disconnecting from the internet.
    • If char.png in the game files is replaced with a custom skin, this will be used instead when disconnected from the internet.
  • Mobs in Indev used the default player hurt sound. They did not have their own special ones, as seen in modern versions of Minecraft.
  • In an early version of Indev, your character in the inventory screen was Rana, used as a placeholder.
  • The screen will sometimes go black after you generate a world set to the "Floating" map type. This may happen because "Floating" map types used a slightly different file format, which prevented you from converting them to Infdev.
  • There is a rare glitch that when you punch a sheep, it will drop magenta cloth instead of the normal gray cloth.
