Call of Duty: Modern Warfare added a new map with this week's mid-season update - and it's got a rat problem.
Exploding rats, that is.
The Cheshire Park map, a classic three-lane map set in a lovely part of London, has a cool Easter egg it didn't take the Call of Duty community long to find at all.
THERE MAY BE SPOILERS AHEAD.
In the middle of the map there's a statue of the Pied Piper, the titular character of the German legend.
It turns out the map has five mouse traps scattered around the place, seemingly at random. Only one spawns at a time, so you have to shoot one trap to make the next spawn. Shoot all five and a piece of cheese spawns at the location of the last trap. Pick that up.
The game then spawns a wheel of cheese, again in a random location. Hunt that down and pick it up.
Take the cheese back to the Pied Piper and offer it to the statue, via button prompt. I know, I know, I camembert this, either.
Once you've placed the cheese wheel beneath the statue, the Pied Piper will blow out a tune of bubbles, summoning an army of rats. These rats then explode in a colourful cacophony of confetti. Gouda job, soldier!
Modern Warfare bills itself as a super serious military shooter, but since launch it's let its hair down with some silly character and weapon skins and plenty of fun Easter eggs. This one, though - this one's brielliant.
