Imagine 4 games. Despite being wildly different on the outside, they all share the same internal framework, known as a game engine, under the hood. Games 1, 2 and 3 are publicly released games, while Game 4 is unreleased and in active development, being the primary driver of new work on this shared engine. Sometimes, Games 1, 2 and 3 get updates to bring their internal frameworks up to date with the newer, actively developed internal framework currently being used for Game 4. By scanning the files and data for each update to Games 1, 2 and 3 and comparing it to what was there before, we sometimes find strings and development information on Game 4.
Games 1, 2, and 3 in this instance are Dota 2, CS2, and Deadlock, while Game 4 is HLX/HL3.
