>From what I understand, this was made to test out some post production techniques and became something more.
http://www.purchasebrothers.com/Purchase-Brothers-v2-hl1.html "The Escape From City 17 short film series is an adaptation based on the Half Life computer game saga by Valve Corporation. Originally envisioned as a project to test out numerous post production techniques, as well as a spec commercial, it ballooned into a multi part series. Filmed guerrilla style with no money, no time, no crew, no script, the first two episodes were made from beginning to end on a budget of $500." This really interests me as I personally am wanting more and more to branch out beyond my self-imposed 5 minute rule and explore longer form films online.
