Water is a third person puzzle solving adventure type of game with an unique look and gameplay. It's a story about a mermaid, and fish men who aren't fish men. A story that brings you into tears and fears. It's about fish people, harp instruments, swimming, and crazy priests.
Well Water definitely is one of the best mods for Half-Life 2 up to date. Not only does it have lots of new content and a very well done atmosphere, but also some good humor and a lot of very clever puzzles.
It is a rather short mod though, with around 2+ hours worth of gameplay, it could certainly be expanded upon. (A fight against AIR perhaps?)
+ It has no major bugs (I couldn't encounter any)
+ New models (With animations)
+ Its own soundtracks (And well done, too!)
+ Well done puzzles, easy to understand and varied, so they don't become boring
+ A nice art style
+ Varied gameplay, there is combat, exploring and puzzling in fitting succession
- A bit more (ingame) explanation on combat mechanics would be nice (But isn't necessary)
- The conversations could have been fully voiced, I don't think it would have threatened the style the mod is meant to have
