Main EE Quest:

-Obtain Monkey Bombs via the Mystery Box or the Side Quest and throw one onto the manhole cover in the main street that has a blue glow around it, next to a telephone box. Once the manhole has been removed, throw a frag grenade down the hole

-Go to the back of the sewer where the metal door is, and throw a frag grenade underneath the red pipe that is high on the wall. The wall will collapse revealing a new room, where a battery can be collected

-Collect the battery from the shelf and bring it to the radio station that is underneath a telegraph pole, at the far end of the main street (Near the MP40 Wallbuy and the entrance to the Park area) Place the battery ontop of the radio and charge it with zombie souls until it disappears

-3 Telephones will ring around the map in an order, starting in the spawn area/first house, and then the street going down the hill, and lastly at the house near the park or at the power area. There are 9 possible phone locations in total

-Answering the phones correctly will dispense a keycard at the previously used radio, which can be used to open the metal door at the far back of the sewer.
-Inside of the newly opened area will be a cell door with a padlock on it which must be shot off using the Death Machine, doing so will allow access to the cell which contains the MK-X Dark Ray Gun

-Use the MK-X Dark Ray Gun on 4 clocks around the map. The first one is behind a barrier in the first house's kitchen, the second is behind a barrier in the same house just before you enter the garden, the third is inside of the pub where a perkslot can be purchased, and the last is inside of the house next to the park. The clocks will have a blue glow around them. Shooting all of the clocks will turn the map to nighttime

-Collect 2 parts around the map (located at the water-fountain and the shelter in the park) and build the antenna at the crafting station in the garden of the house which contains Deadshot
-Take the antenna to the radio in the power building to carrying the signal. After 20 seconds you'll be able to pickup the antenna again and then bring it to the radio in the downhill street, and after another 20 seconds you can then use it on the radio in the spawn area, next to the telepad. Once the signal is transferred, the map will return to daytime

-Activate the telepad to begin another Lockdown Sequence. Completing this will award the entire team with a Perkaholic

-Upon completing the Lockdown Sequence you will be able to Enter the Arena by paying 65,000 points

-Complete the arena by collecting souls into the Crystal in the middle of the forest

-Once the Crystal is charged, it will kill any remaining zombies and the ending cutscene will begin to play before ending the game
