ETC is a classic mod at rtsl.com This remod will bring source engine some features back (powered by trinity render)
This Remod is literally a downgrade of two good mods. Softlocking bugs, wacky and non-consistent visuals (some textures are upscaled, others are blurred), sometimes terrible sounds in ETC 1 Remod and missing enemies in ETC 2 Remod.
Play it only if you like HD-fied everything and custom weapon models. If not, try originals mods instead.
