Delta is a single player modification for Half-Life 1. The protagonist Nick Farell, technical engineer complex "Delta Base", whose duties include maintenance of generators. Unfortunately, the protagonist was in the wrong place at the wrong time, as an experiment at the Black Mesa Research Facility resulted in a resonance cascade that teleported extraterrestrial beings from the world of Xen to Earth.
First public DEMO of project 'Half-Life: Delta'. The first chapter. First 8 maps. After many years of development... I hope you enjoy it.
It needs HL v.22.214.171.124 or higher.
// Attention! The plot will be a bit corrected at final version.
