Thoughts on the thread title:
Blue Pill idea #1: Change the Zombie skin to a giant penis. (Viagra is blue, people.)
Blue Pill idea #2: Everyone gets transported to the spawn point of a new map.
Blue Pill idea #3.

Thoughts on the suggestion: It's not that it's too complicated, it's that it completely changes the focus of the game, like I've stated before. The addition of 'findable' upgrades/bonus makes the whole point of the game change.
