Google Zerg Rush: That was an order, soldier
 

Zerg Rush is Google's latest easter egg and it's admittedly a little late for the holiday itself. Search for the term (it's a Starcraft thing), and you'll be welcomed by a point-and-shoot mini-game where your enemy is an infinite number of color-coded, marauding o's. These will proceed to decimate your search results, which is currently a bizarre meta view of people explaining the game's existence. Get your trigger finger ready -- the internet needs you. (You also can publish your final score with pride on Google Plus.)
