这些,颠覆性地说明了尼赫拉斯生前和Combine是敌人,并且彼此了解。Marc Laidlaw(半条命剧情的作者)在接受采访时提供了更多信息:
“ I*m pretty sure Doug was restating something I*d told him; I [am not] clarifying it, since it*s the foundation on which the series continues. What we saw in HL1 was the very end of a long struggle between the Combine and the last of the Nihilanth*s race ... The Nihilanth*s "world" (if it could be said to have) was long since in the past as far as the Nihilanth was concerned; Xen was their final retreat, and they had their back to the wall, as it were, when the fissure appeared that let them spill into our dimension. Xen itself is sort of a dimensional transit bottleneck--an area of continual contention.[2] ”
“我很确信Doug转述了一些我告诉过他的东西,由于这些是本系列继续下去的基础,我不会过多说明。在hl1中我们所见的是尼赫拉斯的种族的残余和Combine之间多年恩怨的终结……尼赫拉斯的世界(接下来看不懂,高手帮忙)Xen是它们的最后据点,当裂缝出现,它们得以进入我们的维度(难道xen和我们不属于同一宇宙?!)之前,它们已经被逼到墙角了。(最后那句看不懂)
