Me personally I think it's a really huge step down from the other missions. My main issue is not only with how short it is, but also how a majority of the time in the mission you are doing errands rather than proceeding.

The first code is okay I guess it's taking advantage of the fact that there are 2 different houses adding a rng element (unless they could only spawn in one house for me it's been that way).

The second code just feels unnecessary and really it feels like it's only used to confuse the player the first time.

Then finally there's the teleporter sequence which is the WORSE part of the mission its practically just waiting for a timer. I know sensei wanted to make the mission unique/special, but the levers can basically be removed, and nothing would change cloakers are glorified stabbers which is a letdown and closing the doors wouldn't ever prevent them from making it inside because they aren't even killed, they just move towards a different door.

Finally, the ending which I actually like it's a new change of pace pushing into an actively spawning hoard, but it just ends so abruptly, and it just feels like a copy and paste of prologue from dvn

One last thing to note is I do really like the new enemies, but I don't really want to say they are what makes the mission unique because odds are they will be used again in the next mission. Fireteam 1 would have been something unique to add to the mission and from what the leaks shown it was promising but you never see them at all they are just mentioned and when you finally do find them, they're all dead... What was the point of even adding Fireteam 1 in the first place?
