Catpocalypse in Team Fortress 2

You'll find plenty of achievement grinders on Team Fortress 2 who create mindless boring maps just to gain a bunch of achievements. So the author of this new map called 'achievement_all_v4' decided to spice things up a bit, alright not a bit, but simply went overboard by adding a ginormous epic laser firing kitty right in the middle of the map. What happens next is just chaos. Check it out below:

You can download the map here or look in TF2's server browser by map name to find any servers running it. Check out Facepunch's guide on how to trigger this awesome turn of events here.

In both corners next to the respawn cabinets next to the striped walls, there’s a func_breakable (keep shooting it – it makes a glass noise). Once you’ve broken that, under it is a button that triggers 'kittygedon'. I guess you need to trigger them both with +use. I might be missing something, though..

If you are still having trouble check out the youtube video guide on how to pull this off via Facepunch here.
