Ah the Med-Tek building! I loved that place! Bumped into like 3-4 legendaries and got blindsided by a Legendary Reaver while at low health, then had a stand off with a higher leveled glowing one for the finale. The level design can be used very advantageously. While there are holes that the ghouls can drop in from and surprise you, bottle necking, stair case footsie a and shotguns worked effectively.
PSA: Guys if you're playing this game and enjoying it, you owe it to yourself to play it on Survival. I'm level 14 and having a blast, and can't see me playing a lower difficulty. You get the entire, complete Fallout 4 experience, and find yourself encouraged to utilize systems and mechanics the game has laid out, but that you otherwise wouldn't have considered with non Survival's ease. And if your aim is on point like myself and other shooter aficionados, ammo scarcity is really a non issue.
