It's interesting looking at this game as it is essentially a tech demo taken place in a scrapped level from HL2. It's less of a game and more as a cool way to look at how HL2 was made. I'd recommend it since it does do it's job and it's 20 minutes long, so if you liked HL2 it's at least worth checking out if your interested. Not much else to say however just kinda meh and ok
