thats however a player interpret this.
The gate is open because navy can enter it maybe?
However good a corsair pilot is in a titan, alone he is just worthless against a cruiser patrol. Unless you come with a real invasion armada, I seriously doubt you can enter the palce without being detected from a way or another.
Yes it is secret - just like area 51 is suposed to be secret, as I've mentionned.
Look, you can be as elite as you want - be the Kossak of modernity if you want, but even that, can't beat a super power. And Liberty is one. Liberty is probably thousands time richer than corsair should be, it can mobilize a force Corsairs cant match (since they are starving, obviously natality should be low)
If liberty cant win in a one on one fight with you, they CAN and WILL swarm you with their numbers. And they can afford to, because Alaska obviously has some of their most scret stuffs over there, and theyd defend it at all cost.
-oh and what does corsair being in sirius since a long time has anything to do? might i remind you liberty was the first settled? that corsairs made a long way from where the Hispania was downed until Crete, a harsh planet isolated from the rest of the world for centuries?
