A few people requested Daily Leaderboards so am giving the people what they want. Scores are measured by the max level reached + max kill streak (you'll notice your max kill streak is now part of the game over screen). Time isn't a factor in the score as I'd like to give people time to plan their attack. This update also brings a new boss at the end of Zone 1 to mix things up. He's pretty easy to beat once you know how (I hate bosses you have to grind). You can even buy his super weapon in the shop (if you can afford it). Lastly, the update optimizes how particle effects work so older systems shouldn't see frame rate dips during large gun fights. Enjoy :)
