Although the idea is interesting, it just didn't work for me - the same goes for some other mini-games. During gameplay you will also sometimes hallucinate due to different chemicals, and the maps reflect this. I loved the flooded parts of the maps and the parts with lava / radioactive materials, and the fantastic map with the Xen laboratory hybrid.
The map architecture is not bad, but it is commendable that it keeps improving considerably during your journey to the end. I liked both, the dialogues between you and other characters, and notes, which give you some insights into past and present happenings in Black Mesa. The story takes place in parallel with the original incident, but in another part of the laboratory complex. But at that moment everything goes wrong. Omstein, is fed up with your incompetence and fires you at the spot.
You arrive for work a few minutes before the alien invasion, but unfortunately, you are late again. In Life's End, you play a scientist named Luther Johnson, who works in the mathematics department of Black Mesa.
