Infiniminer

Infiniminer is an open source multiplayer block-based sandbox building and digging game, inspired by the games Infinifrag, Team Fortress 2, and Motherload, in which the player plays as a miner searching for minerals by carving tunnels through procedurally generated block-based maps and building structures. Infiniminer is commonly associated with Minecraft for giving Markus Persson (Notch) the idea for where to go with Minecraft, and is often regarded as a direct forerunner.

History
Infiniminer was developed by Zach Barth of Zachtronics Industries with the help of his friend Chris Gengler in their spare time, and released in steps of incremental updates during late April and early May of 2009. It quickly garnered a following on message boards around the internet, and inspired Notch to start working on Minecraft shortly after it was discontinued.

Like Minecraft, Infiniminer is a block-based mining and construction game. Players can play on one of two teams, Red or Blue, as one of four classes: Miner, Prospector, Engineer, or Sapper. Each class has their own set of abilities, tools, and blocks they can build with, with each costing a certain amount of metal ore to place. Many building blocks are team-colored, and most exist to serve a specific function rather than being purely decorative. Players and tools are represented by flat sprites rather than three-dimensional objects. The sky is perpetually dark, and the landscape is made up entirely of bare dirt, stone, ores, and lava blocks which flow similarly to liquids in Minecraft classic. The maps are limited in size, and walking off the edge or digging through the bottom causes the player to fall into the void and die.

Infiniminer was originally intended to be played as a team-based competitive game, where the goal is to locate and excavate precious materials such as gold and diamonds, and bring the findings to the surface to earn points for one's team, until the winning team reaches a certain amount of points. However, as the game gained popularity, many players decided it was much more fun to build things than to compete for points.

Zachtronics discontinued development of the game less than a month after its first release, after a major source leak was discovered due to the developers forgetting to obfuscate a new release, which allowed players to make unauthorized modifications to the game. Soon, there were players using modified clients to cheat on servers, and multiple communities arose each with different versions of the game, and it was hard for the developers to maintain Infiniminer, resulting in further development ceasing and the game becoming open source. In 2015, the Google cloud server for the game was shut down, making the server browser nonfunctional, but the game is still available for download, and the source code of Infiniminer is available under the MIT License. Building Infiniminer requires Visual Studio 2008 and XNA Game Studio 3.0.

According to Notch, Infiniminer was "the game I wanted to do". Notch enjoyed the game, but found it flawed, noting that while building was fun, there wasn’t enough variation, and he thought that the big red and blue team-colored blocks were "pretty horrible". He believed that a fantasy game in that style "would work really really well", so he created a simple first-person engine in the Infimininer style, reusing some art and code from multiple earlier projects, to create the cave game tech test, which would eventually go on to become Minecraft.

Trivia

 * Infiniminer was not the first block-based game created by Zach Barth: Infinitron, Intelligent Destruction and Infinifrag and were similar and earlier games in the so-called "Infinifranchise". However, Infiniminer was the first of these games to have gameplay focused on collecting and using resources from a natural environment. The Infinifranchise has continued with the more recent Zachtronics game Infinifactory.
 * The default port of 25565 used for Minecraft servers is directly copied from the port used for Infiniminer servers, 5565. c0.0.15a-05311904 actually uses the port 5565 but it was changed to 25565 in an unknown later version.
 * Infiniminer has several death messages:
 *   was killed by a misadventure!
 * Appears when the player falls into the void.
 *   was killed by gravity!
 * Appears when the player falls from a high hight.
 *   was killed by an explosion!
 * Appears when the player is killed by an explosion.
 *   was incinerated by lava!
 * Appears when the player is killed by lava.
 *   was electrocuted!
 * Appears when the player is killed by touching the bottom surface of a shock block.
