The wacky “better models better models” mania started in 2000, when an updated zombie model was sighted in a screenshot of HL1 for the Dreamcast.
Now it’s been 10 years, and numerous mods, individual models and other tiny things have attempted to update HL’s graphics to a higher standard. Some were released, some failed, some are still in development hell (BMS and HL:Enhanced, anyone?).
However, I stumbled upon this interesting little gem. Named HL:Redux, it features numerous new models, textures and other things. Similar to “DiamonD’s Half-Life”. Redux is definitely worth checking out. Video and official site are in the “moors”.
