So, this was the favorite of all missinos/prestige missions up to now. Great scenario, the lack of background music during most of the stage was a great choice, really help building the right mood. It's hard to state if the boss battle should be silent too. And, mostly, I'm not sure if the al missions should have some kind of battle.
Of course a mission, specially with a great reaward, should have some challenge, but I doo belive that with it's background, battle shouldn't be the focus of the mission. I was really looking for some kind of message writen over the tomb for the lost soldiers. Still, one of the best missions idea so far.
Ah, one more thing since it's a mission "outside of Haven", the elevator plataform looks misplaced. It doesn't makes sense with where the mission goes, so it would be nice if there was some other kind of "end mission" device. Maybe, for the story of the mission, the player should come back to the entrance, and maybe leave the enemies only in the way back.
I was also expecting something written on the tombstone.
