Just about an hour long, but it shows in a good way just what the Source-Engine has the power to do. Play it and enjoy!

Now, this is a great little demo but it takes much less than 1 hour to complete it. It's basicly a tutorial and showcase for a lot of money. As for myself im not really into that stuff and therefor dont recomend it. It's just not enough gameplay for that amount of money even if its on sale. I'm usually not that guy who complains on games all the time but i just thought that this wasn't enough for me. Alltough if you do like the concept of this then i can say you can go wild. It's your money so you can do whatever you want with it.
