This twin turret was modelled with Blender v2.68a. It is perfect for game developers to make some cool defend games. It has no texture, just a simple material. The turret can rotate 360 degrees around its z-axis. The cannon itself is made out of 4 seperate meshes, which share the same origin point, which makes it easy to tilt up and down, as you can see on the images. It can be used as stand-alone turret or be a part of a series of turrets eg. on a huge spaceship. Most moifiers in the .blend file are not applied yet, to make it easy to edit some more details to it.
