Turn on the power, and try to get Winter’s Howl, a special weapon used to freeze zombies only available in Five. Leave one person behind before you go to the Lab, that person should teleport to the defcon room, and activate all the defcon switches before taking the elevator down to the lab.
Once the defcon is activated, forget about teleporters. Camp at the elevator down the hall; that way you only need to cover your front, and behind is teleporter as an emergency exit in case you get overwhelmed.
Hold it here as long as you can. If you get overwhelmed, take the teleporter to get to Pack a Punch machine. Once you are inside, two people should defend the windows, and two defend the doors. Winter Howl here would be very helpful as zombies will come in numbers once you have opened this room, and it can clear them easily.
If you don’t get Winter Howl, spam grenades. If you get overwhelmed here, run to the teleporter at the back of the room and survive on the run. You would be running a lot after round 10.
If you get teleported to the lab, teleport back to where you started the round and clear the zombies until you make it to the next teleporter.
If you get teleported to the defcon level, make your way to the lab, and then back to where you started the round, and again hold there as long as you can.
If two of your team mates get teleported to the defcon level, you can either run to the elevator, or hold it there as long as you can. Or you can remove the debris and hold it there.
If they overwhelm you there, you can remove the debris and run around the stairs and you will come across a debris blocking the door underneath the stairs, open it and continue with the same strategy.
Basically you need to keep moving through the teleporters wherever and whenever you get overwhelmed. It all depends on your playstyle and coordination. You can survive longer if you communicate effectively.
You need to 2 to 4 people for this to work. After third round, open the door to the elevator but don’t go elevator. Buy the gun off the wall in the elevator room and camp in the elevator room till round 8.
Leave one zombie preferably crawling at the end of the round 8 and open everything. Get a gun from the Mystery Box and buy Juggernog. At around round 10, activate the pack a punch machine and put your best gun in to upgrade. Once you have upgraded your gun, camp in this room.
General Tips 1# Run Run Run! and keep Running. 2# Group zombies into clusters, and blast them. 3# Teleporter is your Back Up plan, that is, if you get out of ammo. Which you would for most of the times. Too many zombies. 4# You can run away easily being solo, so be quick, and don’t get caught in the cluster of zombies or you are done.
Revive the Teammate
In case someone goes down you have three options. 1# (Requires upgraded ballistic knives) If the person with the knives is alive he will pull them out while the other teammate covers, preferably with ray gun. Shoot your downed teammate with the knife which will instantly revive him.
2# Pull out your gun and cover the guy who is to revive the downed teammate.
3# Throw a monkey, man covering window can do this but don’t leave to revive unless you are only one alive. If something goes wrong or you just get overwhelmed as a last resort you can open the door and run.
