Give them Warmth Achievement

[serieus1]

Any tricks to getting this achievement?

I've tried waiting in Slaughter mode till I had the upgraded flame thrower then go in circles burning everything in sight. I'm unsure if I just didn't get 25 on fire, or if it wasn't simultaneous enough, or if it's not possible to get this achievement in Slaughter mode.

Let me know if you got it and how you did it, thanks.

It is on fire all simultaneously. Skaery had a good strategy on it that helped a lot of people:

How I did it:
1) Wait for the flame thrower to be fully upgraded
2) Wait for a lot of zombies to appear
3) Drive around them to huddle them together
4) Slowly drive backward towards a corner while the hurd follow you
5) When you are in the corner with the hurd right in front of you fire

Thanks for the tip. I'm off to burn some zombies in a corner now.

Edit: I got it. :)
