Now head towards Hallway A and go through a blue-lighted tunnel, up the stairs on the right side and right through the door.

Note that you need to have around 5,000 credits to make your way and it is better if you have a few kills under your belt.

Move through the level to reach other generators, one through the tunnel and the other inside the central dome.

To get an EXO suit, you will first need to activate power, followed by spending a few credit points (750) for Administration A.

You must then rely on your limited gear, but should make it through the initial wave of zombies.

When you start off the game, there won't be an EXO suit at your disposal.

It's preferable you start off the upgrading business with extra weapons damage.

Remember to upgrade your weapon's damage, handling, reload speed and more for a better chance of survival.

The weapons inside a mystery box can be randomised, and although none of them are that bad, it's better if you can save them for more dire situations.

You can find one of the boxes the moment you spawn on your left while you make toward the main hub.

Mystery Boxes are scattered across each stage and offers handguns, assault rifles and even more.

Throughout the EXO Zombies mode, note that you will have access to a plethora of weapons, although none of them come closer to the contents of the several Mystery boxes inside it.
