The new content consists of many new NPCs and weapons, new gamemodes, comprehensive customization and tweaking options, new abilities for the player, and new features to the gameplay, such as level randomization and simple branching in the otherwise linear flow of the main episodes. Finally, the developer also released several sample maps and its own mod to the Steam Workshop to get creators started. SMOD is a single player mod of Valve's first-person shooter Half-Life 2. For aspiring animators, Valve also has the latest versions of Source Filmmaker, the AnimaGraph software, and various effect editors. It is also releasing tools to create and edit models and materials, like the Material Editor and ModelDoc. Currently, Steam is offering beta versions of tools like Hammer, Source 2's level editor. With these tools, fans can now use all of the game's assets to make their own levels and animations. In Valve's announcement, it announced the beta release of Half-Life: Alyx's developer tools. On its official Twitter account, Valve shared a community post explaining what is currently available in the Steam Workshop for creative fans of Half-Life's newest game.

When Valve announced Half-Life: Alyx, it promised to release the same mod support tools that it had in the past. Although Half-Life: Alyx modders have already started making new content, they now have Valve's approval. Today, the developer released new tools for the latest Half-Life game in the Steam Workshop.

Now that avid fans have uncovered every nook and cranny in Half-Life: Alyx's virtual world, Valve is ready to hand its community the keys to its latest creation.
