Prequel for Half-Life. Mod allows to look and take part at the events before the Half-Life. You assume the role of Dr. Gordon Freeman. You will meet Kleiner, Vance, Barney, Rosenberg and others characters.
Although is a good effort to introduce the plot of Half Life, doesn't have any continuity to me. We see nice reskinned characters that are crucial in HL2 plot, but the plot in this mod and its dialogues lacks interest. The alternate between russian and english voices screws the experience of feeling this mod as a real prequel. The puzzles and gameplay are way too plain, so I was never really engaged to them.
If you are really interested in the story of the entire Half-Life saga, this mod could be somewhat noteworthy. Otherwise, I would pass of this if I were you.
Induction - the unofficial prequel to Half-Life. I have to say that this mod, even though it only had English SUBTITLES, was really nicely done. If you like Black Mesa mods, you need to play this. The mapping was pretty good, too! Nice that they put the source files up for use. It's a fun run through, but keep in mind that there is no combat or anything like that. Keep up the fantastic work!
