Heroes of The Storm Starcraft-themed fortress model (fan art) and Blueprint. The Blueprint covers many aspects of the fortress' behavior. The fortress has a vision range, a vision cone, and a line of sight. Targets must be within range and the vision cone to become targeted, the fortress will only fire when targets are within line of sight, and after line of sight is broken return to idle. When a target is acquired the fortress lights change colors to indicate it has acquired a target, and then change back to return to idle. Fortresses can be shut down by colliding (or key pressing while colliding) with the computer terminal in the back of the fortress. Shutdown sequence turns off all lights, guns aim down and turret rotation grinds to a halt.

This is still a work in progress that I am intermittently working on to refine and expand functionality, add a complete set of visual effects, and finally end it with a proper cinematic showcase
