This scared the shit out of me. (More than the game usually does).
It happened in Corporate Lockdown. I was hiding behind some boxes and I heard the Alien approaching. I looked up at the height its head is usually at, expecting to see it and and hope it doesn't see me, but I jumped when some unfamiliar thing came into view. It took me a second to realize it was the Alien, but it was walking on all fours... in the open. Was NOT expecting that at all. I really wanted to take some pictures or record the moment, but I sadly don't have any of that kind of software.
I hypothesize this was a glitch: It was crawling around in the vents and got stuck like that. Maybe it wasn't, though. Maybe this came in an update? Because I've never seen it do that before and I've invested a LOT of time in the game. I wanted to get under a table and see if it would notice me immediately right next to it unlike when it's in a standing position, perhaps proving that this is a feature the developers intended, but I didn't last that long, sadly (the Alien got me in a vent system right before I was going to put it to the test). And if this isn't a feature the developers put in the game, they should.
Anyone else have a similar experience?
