Ancient Laser Turret

Throughout the Martian landscape, ancient turrets still stand after centuries of inactivity. They can be found in some of the lava tubes where visitors from other planets once made bases, attached to abandoned spacecraft, and occasionally even in magical locations where Martian water was once collected. These artificially intelligent machines are stationary, but each can rotate their gun in any direction — making an approach a dangerous endeavor. They detect potential enemies by movement and sound. The good news? The turrets are so old, it doesn't take much to destroy them.
