Typical disaster is a small single player episode for Half-Life. It tells a story about Gordon Freeman's job in one of those dangerous top-secret research facilities.
This could be great if you fixed some stuff, it´s a nice set of maps that requires some experience in certain techniques (i.e: Strafe Jumping). However, it could´ve been a LOT better if you fixed some of the A.I. bugs and if you improved the level design, anyway, i can´t say i didn´t have fun playing it, but some of the issues i mentioned before made it frustating at some points, now as for the plot, i can´t really say it´s great but i guess the story is not what this mod is focusing on. I´d say you should try it out if you want a challenge, but you won´t get a masterpiece.
