Aperture Desk Job datamine suggests a new game might be coming in the Half-Life universe
With the release of Aperture Desk Job, a short game made by Valve to introduce users to the Steam Deck's features, came another set of data for miners to pore over. Notable Valve dataminer Tyler McVicker has found a number of references in the game's code to "Citadel," a game set in the Half-Life universe with rumours going back to 2019. Of course, since this is just leftover data found in Aperture Desk Job, and nothing has officially been confirmed by Valve, everything here should be taken with a grain of salt.
According to McVicker, a significant number of Citadel code comments have ended up in Aperture Desk Job; "way too many to read through in this video." Based on his findings, however, and the code comments he does read, we can get a decent idea of what Citadel might be. He describes it as "a Combines versus rebels, team-based, squad-based, class-based, RTS-FPS hybrid" with a single-player campaign. Essentially, players will control a commander who gets an overhead view of the map and uses bots to fight the enemy. The bots come in different classes, can be customized with different abilities, split into squads, and then commanded individually, by squad, or all at once. Players will also be able to set foot on the battlefield, either as the commander or taking control of a bot, to fight more directly as an FPS.
As McVicker notes, however, the gameplay elements are separate from the data about the Combines and rebels, so the finished game could end up unrelated to Half-Life altogether.
McVicker also found data related to three other possible Valve titles, but doesn't have any information on them. These three games are: some kind of follow-up to Half-Life: Alyx, a recreation of a cancelled Portal sequel, and a Source 2 port of Counter-Strike: Global Offensive.
