Minigun Turret (Bureau)
A laser-equipped stationary weapon platform, it has a powerful but predictable firing pattern, and a limited turning radius. A vey sturdy device, it will often be the first thing made by Tech Commanders, so take him out before he can set one up.
Your Engineers can develop the ability to set up a rapid-fire XCOM variant, for close-to-mid-range encounters. Lifting an alien will have it focus on that target, or you can lift the turret itself, and it will fire at multiple enemies.
