2 aliens at once during mission 6.

[Yukari Penninsula]

I was almost at the end of mission 6 (after setting up the alarm), and I got to see the alien killing looters right in front seats (behind a locker in front of the killing). When his carnage was over, I sneaked from the locker into a bed to better get past him, and he vented up. But RIGHT AFTER he got into the vents, and I mean milliseconds after, the door I was supposed to go through opened and another alien was casually patrolling the next corridor. What...? It didn't kill me though (I died at the fire. Lol), I just found it extremely odd. I know there are more than one alien in the station (I got spoiled), but is it really supposed to happen that early or is it a weird glitch? This is my first playthrough by the way. Difficulty is recommended Hard.

Logically, based upon how quickly it moves around and pursues (happens to be near) you, and just hearing it in the vents, it should be fairly evident that there is more than one alien prowling around. And that "glitch" is really more of a punctuation mark, fortuitious timing that spells the situation out for you.

Yeah but I thought the 2 aliens at once was supposed to happen way later into the game. I'm convinced this was a glitch or a very rare occurence at the least since I haven't read anyone who had this happening during this specific mission. I also learned the hard way how the alien works, he goes up into the vents and he's roaming there at all times until he decides to go back and hunt you down, but there's supposed to be only one alien NPC throughout a normal playthrough. My motion tracker picked up the signals of both aliens, the original and the extra one that spawned behind the door.

I know there's a two alien glitch back when you first tap at a keyboard, followed by an alien dropping down from the vent. When triggered, there will be an alien patrolling the stairs as you go up, whilst another alien will be killing the humans.

So, in your case, perhaps think about something unusual you had done, and then try to specifically recreate that.

However, the game will also troll you when you've been doing well, such as:
- vent drop right next to you, such that death is certain
- be placed on the opposite side of a locked door that you're removing the brace from

Which makes me think that the alien upventing took it "off the board," and coincidentally the game had queued a "troll kill" event. Still, even if considered a glitch, it is one with an incredibly low probability of being reproduced.

At the same time, that the event occurred is consistent with the fact that there are indeed multiple aliens roaming about, even when you first arrive on-station.
