Does anyone here know if the redshirts respawn endlessly in Sector 1? I'm playing on normal and I'm stuck on the final part of the game since several in-game days because the waves of enemies emerging from Santino's bunker are unending. I read somewhere that you can exhaust them either by defending Sector 2 or attacking Sector 1 for several days but that's now working.Is blowing a hole in the bunker complex, rushing into it trough the northern path while hoping to get lucky the only viable way?
