Developed on the Source 2 Engine, Half-Life: Alyx sets a new benchmark for visual fidelity and detail in VR. It features incredibly realistic environments with high-resolution textures, advanced lighting and shadow effects, and detailed character/enemy models. The level of interactivity with objects in the environment is exceptional, designed to leverage VR capabilities. The game is renowned for its atmospheric and immersive world.

Powered by the latest id Tech engine, visuals will aim for cutting-edge fidelity, featuring detailed environments blending medieval architecture with demonic corruption, visceral gore, and spectacular particle effects. Ray tracing and other advanced rendering techniques are expected.

Original score composed by Mike Morasky, featuring atmospheric electronic and orchestral pieces that build tension, enhance horror, and underscore dramatic moments. Sound design is crucial for VR immersion, with highly realistic spatial audio, distinct enemy vocalizations (Combine radio chatter, Headcrab screeches, Barnacle clicks), and impactful weapon sounds. Environmental audio plays a key role in detecting threats and navigating.

Expected to feature an intense, heavy metal soundtrack driving the action, possibly by a new composer or a collaboration maintaining the franchise's signature style. Immersive sound design for demonic roars, weapon impacts, and environmental ambience is a staple and anticipated.

Designed for VR immersion. Health and ammo are displayed on Alyx's left glove. Weapon selection is often done by reaching over the shoulder or via a wrist-mounted menu. The Gravity Gloves provide intuitive object interaction. Inventory (syringes, grenades, Resin) is managed via wrist slots or a backpack accessible by reaching behind the shoulder. Minimal on-screen HUD elements to maximize immersion.

• OFFICIAL SYSTEM REQUIREMENTS for Half-Life: Alyx (VR Game). This information has been adapted to the provided JSON structure. Half-Life: Alyx is a VR-exclusive title with established requirements. The '1080p' and '1440p' tier keys from the template are used here to represent 'VR Minimum' and 'VR Recommended' specifications, respectively. The '2160p' tier has been populated with hardware for an 'Extreme VR / Max Supersampling' scenario, which is not an official Valve-defined tier but represents a very high-end target.
