"In this video a squad of AI Crab Mech Drones attacks a Space Pirate refueling station in a frontal ground assault.



I played some Space Engineers and built the first iteration of a six legged crab walker. It is controlled by an autopilot remote control and can follow waypoints. The walker is armed with a missile turret and can be used for mass attacks on enemy bases.
While not very fast or powerful on its own, it's effective when attacking in groups becaus enemy turrets will have a hard time knocking out a whole group.
Another way to effectivly use the crab walker is to set on patrol mode and use it as mobile sentry. In this role enemies can't reliably scout your defenses because the walkers will be in a different place when enemies are attacking."
