Day 8: Airborne
Chen's plan is almost complete. You have everything you need to escape the Ark and contact the outside world, but the Security forces are planning a raid.
Objective 1: Destroy the Storage Depot Door
You need to be a Soldier for this one. It's easy for a first bit of objective; plant and defend an HE charge, as usual for a Soldier mission. HE charges go off in 30 seconds, so it's never hard to defend them for long enough.
Objective 2: Deliver the Hydraulic Fluid
This objective you can be any class for. A Light body type is useful for running quickly, getting the item and running it to the objective in an attempt to complete the mission as quickly as possible. The enemy will pretty much be surrounding the objective, unfortunately, which means you need either your whole team focused and together, or you need to be fast and accurate with gunning down the enemy.
Objective 3: Hack the Warehouse Controls
This is another of those frustrating Operative objectives, and this late in the game it's bound to be hard. Once you get the fluid to the plane to get it working, you need to go get the Warehouse controls under your control. Operatives are hard to play and disguising yourself as the enemy only works to get to the objective. As soon as you try to hack the controls you remove your disguise.
Objective 4: Deliver the Avionics
This is another package transport mission, and as such can be done by any class. Once the warehouse control terminal has been hacked, you need to bring ANOTHER package to the plane, from the terminal this time. Once again the enemy will be clustered around the plane, and you'll need to force your way through until you can successfully plant the Avionics.
Objective 5: Repair the Fuel Pump
The final objective of the final mission, you need to be an Engineer. There's only one thing left to do to get the plane moving. Repair the fuel pump and you can finally fly this plane out of here. The fuel pumpm is quick to repair, which is good, because it's a very contested area. Use a Light and don't worry about dying, because the progress can't be undone.
There are no side objectives in this mission, which is good because it's so long.
