Simple guide and easy way to get the Road Rage 2 achievement for destroying a hundred cars.
You need to create a custom superhero which can be located in the Avengers Manson, I'm sure you'll know where it is.
- Click on "Abilities"
- Click on "B" or the corresponding button on your input
- Click on "Hold"
- Click on "Beam"
- Click on "Beam Damage Type" & select "Heat Beam"
- Make sure sure "Toggle" has a green strip on, it should be on by default
- Beam Style should be default which is "Beam Style 1"
- Beam Origin should be default "Left Hand"
Once you've done that you should be set for destroying cars. I found it easy to do on the motorway around Kang's Tower. Just move around every now and again or cars may not spawn.
