Hardpoint

Hardpoint Alpha is located in the factory directly next to the docking bay that is easily accessible to titans. Alpha is wide open and can be captured from many different angles. You can’t capture the point from very far away, but if you creep to either side of the docking bay, you can get close enough to the wall that you can remain unseen while still capturing the point.
The best way to attack this point is to come from the backside with a titan, because if you can get close stand right next to the platform you can have your Auto-Titan call out enemies and watch your back as you stay hidden and capture the Hardpoint.
Pilots on foot will have to use the location behind the second furthest energy vat and hide behind it while watching the next level above you to make sure enemies are not coming from the Bravo side. There is a chance that a titan will move towards the docking bay, but if you stay behind the tank, it may not notice you are there.

Hardpoint Bravo is located directly in the middle of the map. The Hardpoint is inside a circular room suspended above a titan sized pathway. This point is extremely vulnerable as there is a mesh floor that can be seen through giving away anyone’s position on the inside.
It is a good idea to defend this point from the outside on the ground with a titan and the Triple Threat, or from the one of the corridors that leads to the Hardpoint room. Grenades and mines are the best friends of a defender as this tuna can of a room is an explosion hotspot.
When attacking be sure to get in there and stay close to the exit. Prepare to leave the room if you spot a mess of incoming explosives, it’s much better to leave while the Hardpoint is partially controlled rather than die and not be able to get back to the point.

There is also an opening at the top of this room which allows for discrete entry or an emergency escape. Once you know the Hardpoint is capture, get out of there as fast as possible and defend it by dropping a few insurance grenades down the hole.

Hardpoint Charlie is located inside the large building adjacent to the giant drill. This building has three main entrances that you will need to watch constantly. The first two are near the front on the corner of the building that lead to the first and second floors, they can both be watched from the third floor. Set a mine or use the Personal Alarm System to let you know when there are enemies coming from the third level door so you can react and defend yourself from intruders.
As mentioned in the defense, this Hardpoint is vulnerable from the third level entrance on the rock near the giant drill. If you lob a grenade in the entrance and take the building from the third level, you can coordinate with your teammates to take the building as you enter hopefully getting the drop on any and all enemies below.
