Winner of over 50 Game of the Year awards, Half-Life set new standards for action games when it was released in 1998.

Half-Life: Source is a digitally remastered version of the critically acclaimed and best selling PC game, enhanced via Source technology.

It is a straight port, lacks any new content or the Blue Shift High Definition pack. Includes vertex and pixel shaders for more realistic water effects, as well as Half-Life 2's realistic physics engine and all other goodies and improvements introduced by Source engine.

Well after searching for the HD Pack for Half-Life Source, I finally found it. The name is High Definition Source Project and they are porting the HD Pack for HL:S.

This adds the HD models and view models and much more to Half Life: Source like the one on the original version that has death animations. Have fun!

No, but you can copy all the maps/materials/models/scripts from OF and put them into your maps folder.

when i compare hl1 and hls i pick hl1.. why? because i can adapt everything i want in hl.. there are LOTS of community made addons and mods + the game itself has faster and more professional gameplay. hls is full of bugs and gameplay quality is pure ****.

Sir, you are wrong. HL1 is the one with the OhMyFricking much bugs. The AI is dumb, almost nothing is readable, and you will get killed most of the time by the evil elevator. In HLS, if you pull a box, it doesn't get flinged away. Plus, HLS has - although still less quality than HL2 - ragdolls. If you take away the addons and HD pack, HLS is better.

Half-Life: Source sucks damn. Uses HL2 Sounds at unmatching situations and is absolutely $$ making.

Buy Half-Life 1, its the complete REAL package, and you can get all those awesome mods. The best mods were made for Half-Life 1.

Ranger366 your right about something yes Half-Life 1 is better than HL:S but only in a few things.For example HL1 has all those awesome mods like you said but the game has alot of gliches like getting stuck and that crap.On the other hand HL:S has realistic ragdolls,better looking water and not much gliches.And if you want HL models into Garry's Mod you can copy the materials,models,scripts,maps and all that **** and paste them is Gmod's main folder and bileive me I tried and it works.So in my opinion both HL1 and HL:S are cool.

You really are a fan of the original Half-Life? Much? You want play it with better graphics? awwww, sorry, but this isn't your game. This only is lazy port made in 2004 with the original bugs of the normal Half-Life and a lot of new ones, also the graphics no are better and only adds a few graphic effects for look more cool (Say hi Halo Anniversary) This "port" only is cool for the content in Gmod and laugh with the stupids bugs and the physics, the game solo is boring and craps totally the original…
