As a little sexy incentive for buying their Season Pass, Irrational Games is offering the Early Bird Special Pack free of charge, which
contains: four pieces of
exclusive gear (I want a bird costume with a worm handing out of its beak because that would be SO CLEVER), Machine Gun and Pistol Damage Upgrades with gold skins for each (no word on whether or not this will result in one hit kills), and five Infusion bottles that can be used to boost stats like health, shields, and the amount of Salt you can carry (which lets you use abilities called Vigors and does not in fact just raise your blood pressure).
