Communication and traveling in packs of two are the most important parts of Hardcore, and any game type for that matter. But it is EXTREMELY vital in HC.

Where do you think the best spots on each map are to try and hold down?

Lockout: Sniper tower.
Burial Mounds: Cov Sniper base.
Backwash: Just stay together really...
Beaver Creek: Roof tops, sticking together and controlling to the OS.
Ascension: Big tower, controlling OS again if possible. Or little tower is decent too.
Turf: No idea...
Ivory Tower: Not played very often, but Sniper spawn point.

Why can't I think of any other boards?
