At the keypad, enter the code "989".
On Episode 3, Part 1, at the part where the wall blows up, turn on your Night Vision goggles and look to your left to find a message from Maggie.
EPDD On Multiplayer
Using an EPDD is very effective when an enemy is
in the water. Just be careful not to be in the
water when tasing someone. You will lose a little
health but anything electronic like goggles and
tasers except for the flashlight will be disabled
for a short while.
