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 guerilla 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 [via ggmania].
