1 0 0This may sound like an incredibly daunting task, but it actually only takes about 10-15 minutes. Once you are nearing the end of Episode 2, Barry will be in a cabin and complaining about weird birds. The birds will then begin dive bombing Alan, and you will need to kill the flocks before you can progress.The only way that birds can be killed are with Flares, Flare Guns and the Flashlight. Right before this section, if you went to the emergency box in the second-last safe haven, you should've gotten a Flare Gun and some ammo. Save that ammo, kill the six Taken, and progress onward to the cabin and to another safe haven. This safe haven has more Flare Gun ammo. You should have 5-7 Flare Gun ammo by the time you get to Barry. Simply expend all of your ammo when the birds are dive bombing you, and then reload your checkpoint. You will be at the safe haven closest to the cabin and with all ammo in tact. Continue this process until the achievement unlocks.
