This is very easily the best co-op Half-Life experience you can have. It has the slightly crusty Xbox 360 gamechat, the whole campaign, and even more content in the workshop or with mods! You can even play through the expansions: Blue Shift and Opposing Force with friends! All this requires is one private password locked server (which you need to host) and having the expansions on your account. That way, if you already have them, your friends don't need a copy (unless they plan on playing solo, of course). I also played this before I was actually able to afford the main game a couple years back. Think of this as a trial if you don't own the actual game yet. So I completely recommend this, but I also recommend getting the base game + expansions for yourself. They are all great games!

Pros: no hats!

Imagine Garry's Mod but HL1, also yes, you can basically just play through the half-life campaign if you want.
