《半条命2:第一章》是《半条命2》的独立资料片,于2006年发布,无需拥有原版游戏即可游玩。游戏紧接前作剧情,玩家将扮演戈登·弗里曼,与艾莉克斯·凡斯合作,在被战火摧毁的17号城市中稳定即将爆炸的联合军基地核心,并协助市民撤离。作为三部曲中的第一部,它提供了更紧凑的叙事体验,并利用了Source引擎的升级,尤其在面部动画和高动态范围渲染方面有所改进,核心玩法依然是第一人称射击与物理解谜的结合。

\n故事背景紧接上一部作品的结尾,玩家将再次置身于饱受战火蹂躏的17号城市。核心任务围绕科学家戈登·弗里曼和他的盟友艾莉克斯·凡斯展开。他们必须争分夺秒稳定一座正在失控的联合军基地核心,以避免其爆炸摧毁整座城市及周边区域。完成这一关键任务后,重点转向紧急撤离行动,协助尽可能多的平民逃离这座正在崩塌的城市。
\n作为计划三部曲中的第一部,本作提供了一个比前作更聚焦、更紧凑的叙事体验。它沿用了相同的世界观和基础机制,但作为一个高风险的章节,旨在解决紧迫的剧情线索并推动宏大的冲突发展。
\n该资料片充分利用了自《半条命2》发布以来对Source引擎进行的大幅技术升级。主要的改进包括引入了高动态范围渲染能力,以及显著升级的面部动画系统,这使得整个战役中的角色互动更加细腻和富有表现力。
\n\n游戏保留了前作标志性的物理谜题解谜、紧张的第一人称战斗以及环境互动相结合的玩法。本作一个显著的特点是加强了弗里曼与艾莉克斯·凡斯之间的合作,艾莉克斯的协助对于推进许多挑战至关重要。

\n\n这款资料片可在多种平台上运行,包括PC (Microsoft Windows)、Mac、Linux、Xbox 360以及PlayStation 3。

Return as Gordon Freeman in a new VR adventure to City 17 and beyond. Deal with the consequences of your actions in Half-Life 2 with this community-made adaptation of Episode One to glorious roomscale Virtual Reality!

This mod allows Half-Life 2: Episode One to be run under MMod. The goal of Half-Life 2: MMod is to enhance and expand gunplay, combat mechanics and the immersion factor by giving the Player more options and combat opportunities as well as refine how the Player handles his arsenal. Half-Life 2: MMod also offers minor AI enhancements, extended abilities for combine soldiers ( dynamic jumping, firing smg1 underbarrel grenades, shotgunner double blast, etc. ), multiple bug fixes, enhanced visuals, VFX re-design, sound redesign and much much more, while keeping nearly every new feature in the mod totally optional.

In Minerva, the player character is an anonymous person (who is hinted to be a renegade Overwatch Soldier in the in-game messages) who has either acquired or been provided with a stolen HEV suit. Guided by the mysterious Minerva, the player character is deployed on a tiny island occupied by the Combine - an island which hosts a huge facility - with the goal of infiltrating it and discovering its purpose.
