At one point during the game’s development, we were planning on having the Destrozar shoot bullets from its smaller side turrets.  I made a bullet texture that I used for both the bullets and the particle that emitted when the bullets hit a surface.  The bullets themselves were just three or four intersecting planes with the material assigned to them.

It was pretty cool having Destrozar relentlessly shoot at you, but we ended up not including the feature in the final build.  That said, the functionality was still in the game, so I turned it back on for the sake of the video.  I also made it so the shooting was continuous and endless, because why not? 😛
