Quest 5
Quest 5, commonly just called Quest, is an authoring system published in 2012 for Interactive Fiction. It creates XML files with the extension .aslx, which can be edited either in an official, GUI-based editor (written in a combination of C# and Visual Basic. NET), or as plaintext. The editor contains a feature to "publish" these as .quest files, which are ZIP files containing the original .aslx as well as supplemental files. The .aslx or the .quest files can be played either in the editor or in a "web player" (which uses the same backend as the editor).
Quest 5 should be confused with neither Quest versions 1-4, which it superseded but is distinct from, nor QuestMaker, which is entirely unrelated aside from being another interactive fiction format.
