Scapegoat

So a health system with the visual bar replaced with differing levels of constant shaking/rumbling?

Gutted! Saw this in the morning but didn't have enough time to grab it.

Can those outside of North America even redeem the Consul's Car DLC?

A good tip I can give is for every question that you doubt/believe is a lie always select lie first.  
 
A lot of the time when you select Lie, Cole will ask another question which is the fact you must prove/disprove. This often deviates from what the original question was dealing with. If you're wrong, you can just back out of the accusation all the way back to the question ask page.

Oh, man, can't believe you're missing THIS one. I saw SO MANY of those near central police station.

I finished my collection yesterday, and here's a way to help you that will seem crazy, but I swear it works. Go to the Showroom, search the car you're missing (only works for 2 and 4-doors vehicles), press A or X over it. Now go back to main menu, cases, Homicide Desk, Free Roam.

As you start, the vehicle will pass by near you, or it will be parked across the street. I swear, I got every 2 and 4-door cars I was missing that way.

I have never heard a song by them. This is going to sound really dumb, because it is, but their name totally turns me off. I just think that Arctic Monkeys is a really stupid name for a band.  

Please tell me something about your personal appearance, I want to make you feel bad about it.

Huge fan of the band so very biased. Loved Suck It And See along with all their other albums. 
 
Very interesting hearing the different versions of Piledriver Waltz (album vs Submarine version) though I think I prefer the movie version.

Too late! Congrats to the winner.

The only ones I really know of are Synergy, which you have already stated, Obsidian Conflict and I believe Garry's Mod has a way to playing coop. But to be honest I am not sure that any of them were specifically made, or have the ability to play Half-Life: Source. Most of them seem to focus on HL2 or custom coop maps.  Although, to be completely honest. If you have the original Half-Life or can spend $10.00 to buy it, the Sven Coop is almost absolutely your best way to enjoy co-op play with the original Half-Life. Also, if you are feeling up to it, you could purchase the Half-Life 1 Anthology for $15.00 on steam and I believe Sven Coop supports Opposing Force and Blue shift as well. Not only that, but Sven Coop has mad amounts of really fun user created Half-Life style of coop maps. I know your wanting HL:S, but considering it's a pretty shitty port, I would really go with Sven Coop.  Hope this helps. :)
