Re: Nova Garon stuck on merrin rescue
@58458621 I believe the sequence is that when Cal and Merrin have killed all the enemies, a cutscene triggers with Denvik arriving and Cal deciding how to deal with him. Once that's finished and the player regains control, Cal can exit the hangar through the entrance Denvik used, then loop around to an elevator that leads to the upper hangar where the Mantis is waiting.
Where are you in this sequence, and which door won't open? A screenshot or two would be helpful.
