very nice mod love the look of the base and the puzzles, the ending made me leave with a smile :) 9/10 wish it had more weapons to use and more npcs to fight but at the end of the day it's a puzzle mod, if love half life download this mod :D

Incredible mod. Displays that creativity can always be found within the existing game mechanics.
