Alright, here is a challenge for you people, this will take a LOT of effort.
Has to be 100% legit, no cheating, hordes enabled, static spawn, no using time dilation.
Find a lot of external gas tanks for your vehicle.
Horde them all.
Fill them all to 100% with gasoline.
Find a large town/city. The kind that when you stand in the centre and look at the over-world map, the city takes up at least more than 50% of the screen.
Enter the city, not killing a single enemy the entire time.
Scatter the gas around in strategic locations, making sure you have enough for each building to be affected by the chaos to come.
Place one in the centre of the city.
Stand beside the gas tank and use a really loud device to attract zombies from the whole city to the centre of the map.
Attract as many enemies as you can until the last moment where you have to get out or you will be stuck.
Leave a “radio dynamite” next to the gas tank you were at in the centre of the city (Or timed C4).
Escape the city alive without killing ANY enemies.
Put on “Stylish Sunglasses” not the normal kind.
Detonate the dynamite. (Or wait for the C4).
Listen to the countless explosions going off throughout the whole city, as one gas tank explodes another and another like a deadly explosive game of domino’s.
Now here’s the challenging part;
Don’t look back, just keep walking away from the city and never return. No, you’re not allowed to inspect the glorious carnage you just unleashed. Ever.
If someone can achieve this, then I will hail them as a God of the Cataclysm.
However I admit I would love if someone failed at this by going back to inspect the carnage to post before/after screenshots.
