''TIS-100'' is a 2015 puzzle video game developed by Zachtronics Industries. The game has the player develop mock assembly language code to perform certain tasks on a virtualized 1980 computer that has been corrupted. The game was released for Microsoft Windows on the Steam's Early access program on June 1, 2015, and OS X and Linux versions followed a few days later. A final release followed on July 20, 2015. ==Gameplay== Within ''TIS-100'', the player is said to have come across a malfunctioning TIS-100 computer ("Tessellated Intelligence System") and its manual, based on early computers of the 1980s. The computer is presented to the player as twelve separate processing nodes laid out in a four-by-three grid. Each node has a single processor register to store a numerical value as well as a backup register. Nodes also hold their own assembly language program as entered by the user. The assembly language, a simplified version of real-world assembly languages, allows the node to accept external input or a numerical value sent from an adjacent node, perform basic math and logic operations, store and backup the current data value, and then send results to an adjacent node or to the program's output. Later puzzles introduce nodes that have the ability to manipulate a simple 4-color graphics display. The player is presented with a series of puzzles that require them to program the nodes to perform specific actions on a set of numbers from one or more input terminals to produce pre-determined output at other terminals. For example, one task requires the player to double the value of the input at the output terminal. The game presents the list of inputs and the target output values that it is expecting and requires the players to develop the code for each node to match this; if during execution the output nodes receive unexpected outputs, the execution will cease and the player will have to rework their solution. Not all nodes are available in certain puzzles, so the player will need to route around these nodes. The game offers the player the ability to step through the execution of the code and insert debugging statements to determine logic issues within their code. Once the entire input is consumed and target output conditions are met, the player is considered to have solved the puzzle. The nodes that are disabled in puzzles contain cryptic messages related to the narrative of the game and which contain more information that can be accessed when the entire game is completed. As with previous Zachtronic games like ''SpaceChem'' and ''Infinifactory'', once the player completes a puzzle, their solution is compared to other players through online leaderboards. The player is ranked based on the number of nodes used, the number of instructions within their code, and the number of executed instructions. The game allows the player to return to earlier puzzles to better their solution. The game launched in Early Access with about 25 puzzles within the game, and another 25 were added by the time of its official release. The game also includes undocumented instructions. HCF is the first known undocumented instruction. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「TIS-100」の詳細全文を読む スポンサード リンク
