If a written guide is more your style, i'll try to write one here:
1. Load up Mission 5: The Queen's Fodder in the IPSILON campaign area.
2. Build a small vehicle with pivoting front tires.
3. Put a bar across the front and back of the vehicle.
4. Attach 3 drills to the front and back on the front/back bars.
5. Attach metal spikes to the tires.
6. Reinforce the tops of the wood with braces, or it will break.
7. Try to drive slow, and get everyone's attention, so they swarm you.
The vehicle will likely break and spin, wiping out everyone around you. That is why it's important to get everyone's attention so that then convene on your area, and walk into the spinning death machine.
