Experience Half-Life 2 like never before. Return to City 17, held within the iron grip of the Combine and the Consul. Reunite with old friends, and enemies. Traverse vicious canals, make new allies, and brave the horrors of the Quarrytown. Immerse yourself in a revitalised combat system featuring old arsenals made new again, with added features to raise the bar in gameplay. You've been waiting for quite some time, now. It's time to climb aboard.
Overall I would say that I enjoyed the demo. The beginning sections before you reach the lab tended to feel a bit barren and stretched out. There wasn't a lot of interactivity with the NPCs and the walking around section could have been shortened a tad. The main enjoyment I got from this section was recognizing some of the map sections I had seen in the beta.
The voice acting for Barney was alright but the tone (or audio quality?) sounded a bit out of place sitting next to Kleiner when they were talking.
Once you're given weapons, things start to improve. I felt like the levels for gunfighting were well laid out and quite fun. I don't think this section needed to be quite as long as it was either but it did make up for the beginning.
Asides from what I've already mentioned, the ending of the mod is a bit sudden and just kind of happens. Also, I noticed on several occasions the NPCs (mainly citizens) bugging out or acting weird. Lastly, I'm not a big fan of the new headcrab design.
