Attackazoids

ATTACKAZOIDS! and it's prequel ATTACKAZOIDS, DEPLOY!! are a series of short Sci-Fi/Horror films by the group Robot Hand. Set at an unspecified point in the future, they tell the story of walking war machines used to supposedly quell an insurgence on another colonized planet. Of course, things go horribly wrong.

According to the end of the prequel, a third film, entitled ATTACKAZOIDS, UNLEASHED!!!, is in the works.

The original film can be viewed here, and Deploy here.

Tropes used in Attackazoids include:

Cool Old Guy -- We may not be completely sure what's with the old man in the first film, but he seems pretty Badass.
Eyepatch of Power -- Grand Executor Corman
High Octane Nightmare Fuel
Humongous Mecha -- The Attackazoids, of course!
Kill'Em All -- Apparently the Attackazoids' way of going about things. This also seems to be what happens in the first film.
Scrapbook Story -- Deploy is portrayed as an old-school propaganda newsreel encouraging people to buy "Attackazoid Bonds".
Stepford Smiler -- Ms. Ruthers
Unreliable Narrator -- There are a few things depicted in Deploy that don't mesh with what we see of the Attackazoid assault in the original; this can either be attributed to some part of the story we haven't seen yet, or Deploy is warping the truth (which wouldn't be surprising as it is propaganda) to suit the militaristic cause.
