Well, considering that I have now beaten RE6 (Or at least part of it)...I'd say that it's pretty Resident Evil-y.
Just throwing out a random example, there's a point where in one of the stories, you're trapped inside of a ship that's about to go under. The door leading to the hanger, the only way to escape, is locked with three keycards because WHY NOT? A new enemy is introduced here that can't be killed but can be incapacitated for a moment. However, in areas with water (Mind you, this is a partially flooded ship) they can't be incapacitated at all because they use the water to revive themselves. Also, damaging them enough causes them to split into two pieces, which will eventually form two new entities. They're also more or less immune to melee attacks, as most of the higher tier enemies are. Another feature is that they'll tear off their arms and throw them at you, which will damage/blind/restrain you while they slither closer to finish you off. The disembodied arms are also autonomous and will chase you independently of the host.
Tight corridors, infinitely replicating enemies that are effectively immortal, and you've just come out of a series of large firefights with NU soldiers, so ammo was likely running a bit tight from the beginning without the ability to fall back on melee if you run completely dry. Gets pretty tense.
Edit: Also, for some asinine reason you have to swipe each keycard independently, which means that the monsters have enough time to catch up with you if you managed to shake them.
