Modder.
One of the best modifications for Half-life!
Surprises with the design and the atmosphere even now!
Never I regretted the spent time in this modification
Interesting modification about opposition of two worlds.
It is a pity that nobody plays it
Interesting modification in style of a platformer.
Good, there is even a multiplayer
Wow! Here even there is an instruction on creation of levels to this modification!
It is worth playing this modification for the sake of the frightening atmosphere, the weapon from Half-life 2 and pleasure to kill monsters from a Half-life version beta
Good modification with cool level design and the standard gameplay
