Center Hardpoints
Defending the Center Hardpoint from inside the bunker is likely your best option. Hardpoint tends to be much more chaotic than most other objective-based modes, so while it wasn’t recommended for Domination, the spawns will switch up enough during this mode that it’ll be hard for either team to attack with a united front. In short, everything’s crazy, so hide.
Southwest Tower Hardpoint
Southwest Tower is likely the most difficult point to capture and hold, if for no other reason than it’s heavily fortified and favors defenders. Scorestreaks and grenades will help dislodge enemies, but your best bet is to simply get there first. If that’s not an option, you can try flanking by climbing up the south wall in Main Flak Gun, which will likely be your best bet if your team is attacking the other opening at the Satellite Spawn.
Elevator Room Hardpoint
A good option for contesting or defending the Elevator Room Hardpoint is to sit in the small room at the top of the stairs. You’ll need to watch out for grenades, assuming enemies suspect your presence, but you’ll effectively cut off line of sight from any attackers. As an added bonus, there’s a ladder on the window’s outer wall that leads right into the Hardpoint, so you can access the point with ease.
Main Flak Gun Hardpoint
Main Flak Gun is one of the easier points to contest and capture, but tough to hold. Cover is severely limited and there are plenty of ways to flank anyone on the Hardpoint. Try to stay alert, keep moving, and aim well.
If you’re trying to take the Hardpoint from the enemy, attack from the north or south rather than from the center. Main Flak Gun has the most cover when facing toward the center, but barely any cover to speak of on its north and south sides.
