1. Melee enemy personnel (x10)
You will need to take control of one of your infantry units and eliminate enemy soldiers using melee attacks. There are heaps of enemies about so 10 is not too much of an ask.
2. Eliminate enemy personnel (x20) using sentry turret
There is a sentry gun up on the helipad with Objective B, from here you can look down at the road and kill any enemies nearby. kill 20 enemies over the course of the mission with the turret to complete the challenge.
3. Eliminate enemy personnel as CLAW (x10)
Take control of an CLAW and use it shoot and kill an enemy infantry unit (or any unit for that matter). Repeat another 9 times to complete the challenge.
4. Complete mission with enemy never lowering defense field
You will need to prevent the enemy forces from capturing any objective marker for 10 minutes. This is most definitely the hardest challenge on this map. To do this, you need to send the majority of your troops to Objective C, have th CLAW guard objecive B, whilst you man the turret at objective A. You’ll want to frequently switch to tactical mode to keep abreast of the situation and quickly assume control of a unit at another defense point if you think it necessary to turn the tide back to your favor. If its still too tough, try reducing the difficulty and trying again!
5. Eliminate enemy ASD (x3) using only sentry turrets
There is a sentry gun up on the helipad with Objective B, from here you can look down at the road and kill any enemies nearby. kill three ASDs with the turret to complete the challenge.
6. Eliminate enemy personnel (x20) with headshots
You will need to take control of one of your infantry units and eliminate enemy soldiers using head shots. There are heaps of enemies about, so you should have no shortage of bad guys on which to attempt popping heads.
7. Destroy enemy quad drones (x12)
Take control of one of your units on the ground and use them to destroy the quad rotors that appear. Most will come and attack Objective C. Once you have killed 12 the challenge will be complete.
8. Prevent enemy from planting more than one hacking module
As the description indicates. do not allow enemies to capture more than one of the objective markers.
9. Allow no more than one sentry turret to be destroyed
An easy way to do this is simply to jump into an infantry unit, pick the auto turrets up one by one and put them away in a quiet corner where no enemies will attack them. It will make the defense a little more difficult, but you will earn the challenge!
10. Complete the mission in "tactical view" only
As described. As soon as the mission starts, switch to tactical view and don’t exit it for the remainder of the mission. Follow the guides above and you should be able to polish them off without much trouble.
