Half-Life: Element 64 is a new mod that launched its demo on Steam, focusing on fast-paced gameplay similar to earlier classics like Quake. The mod features new levels and music while retaining some elements from the original game. Players can engage in combat against head crabs and vortigaunts in a level-select hub. The developer, Dark Vector, is working on hotfixes for the demo and has plans to unveil Half-Life Arena in two weeks, which is a deathmatch overhaul inspired by the PS2 version of Half-Life. A release date for the complete mod is not yet announced.
