| 1 |  Defend Ground Station contracts are marked on the map with a skull shield icon on a blue cellphone. Players will need to collect data from seismic refractors before starting the defense part of the contract. ▶︎ How to Complete Defend Ground Station Contract |

| 2 |  Mercenaries will drop from time to time while the computer uploads data. A good way to hunt for mercenaries during the contract is to keep an eye on smoke screens in the surrounding area, these are where the mercenaries drop to halt the upload. ▶︎ Zombies Best Guns and Weapons Tier List |
| 3 |  In our experience the main threat with this contract is the shielded mercenaries as they protect other mercenaries from your shots and breach through your defense. Take the shielded mercenaries out by throwing a Semtex at them or flanking their exposed areas. ▶︎ List of All Zombies Gear |
| 4 |  The Death Perception Recipe will be inside the reward rift once the contract is finished. To Exfil, look for the icon of a person stepping out of a doorframe. You can exfil by successfully boarding the exfil helicopter after calling it and defending the landing zone. ▶︎ How to Exfil |
Having other players for this mission is extremely helpful as they can ping the mercenary drop points while defending the ground station. Your teammates can also be assigned to defend each side where mercenaries might come from.
