You might remember the popular Half-Life 2 short Escape From City 17 that David and Ian Purchase created back in 2009. Well, they've finally followed it up with a second part, and it's pretty darn amazing. Here, just watch it: According to the brothers, this was done on a budget of $250, and donated software, time, and an HVX200 camera. Pretty impressive, wouldn't you say? Just imagine what they could do with a real Hollywood budget...
