Have you seen any of the other Chalk Warfare videos? Here’s the link to Chalk Warfare 2.
The series is essentially a demonstration of special effects and movie making skills. That said; the writing and ambition has gone up with each video and there are plenty of nice little twists in Chalk Warfare 3.0 that make it worth watching even if you’ve seen the first two. In particular there are plenty of extra geeky weapon references in this one.
