I desire the fragment sword, roit naow. Lvl 574 M4X P0W3R, 11d 10h 21m 17s idle, 18505 quests, 30k hot sauce and thinking rose_dude's suggestion... could actually work.
This could totally turn into an RPG or even an MMO. Select a person from the crowd to be, run around like in Endless Zombie Rampage attempting to protect your town, and build up a group of people to set up a bunker and defend from the zombies. Mash that together with other players, and this could be one EPIC game. It's already pretttttty awesome. 1k civilians with 100% armed and 100% accuracy + max cops vs 2k zombies max speed and 1s infection time = civilians PAWN teh zaombiez.
Lol if you click the period in the "I like turtles" achievement after it says "You know he secretly likes it", it takes you to a youtube vid where a kid dressed as a zombie with zombie facepaint goes "I like turtles!" for a news interview xD
AAAAAAAAUUUUUUUGGGGGGGGGHHHHHHHHHH, the 16 swans achievement is gonna give me a freaking SEIZURE... who the hell lets out that many aircrafts over about 20 buildings!? And they AIM for the geese?!
