sentry gun from Team Fortress 2
Finally got around to the turret, and I fixed the 3rd part which was filmed 6 months ago . At this stage in the video is completely finished work in appearance and electronics, looking at before I will say that the shooting equipment is already installed in the turret and runs the setup. 4 second part (it is final ) not going to tighten and it will be released as a video or using one .
