The greatest Half-Life modification ever made. You can't play BooM... BOOM PLAYS YOU!
This mod has a gripping storyline about the Boomer, a young boy who sets out on a journey to break as many crates as possible to find his lost sister. The controls are superb, making perfect use of the customisability of the GoldSRC engine to address issues found in the original Half-Life, and map design is incredible, pushing the engine to its limits with fantastic lighting, high-polygon structures, and wide-open areas, yet the mod manages to have brilliant r_speeds and does not lag at any point. Enemy encounters are well designed, custom scripted sequences are thrilling, and, in general, this mod is just perfection itself. Custom textures are high-resolution, using heavily modified DLL files to provide much higher resolution than stock GoldSRC could support, and a similar thing has been done for the sounds, allowing them to play at 48khz with no choppiness or sync issues. All in all I give this mod 42 out of 5 stars.
