This game footage is rubbing me the wrong way. By lore, Aliens are incredibly fast predators who can smell you extremely easily, meaning that the moment it sees you, it will pounce and rip you to shreds. This could either make the game very hard and intense, where even seeing it causes it to catch you every time, meaning a twitchy use of you motion scanner is required. Or, the game would make the alien move slower for "reasons" just so you have a slight chance. Even if they were good reasons why the alien is handicapped, it might take away from the experience. Hard to tell.
But what really stood out for me the puzzle with the blow-torch. "CUT Panel in Emergency." Ok, what kind of idiotic safety measure is that? No engineer in their right mind would make an emergency cut to open panel. Let's say the ship is crashing into a planet, you are at the emergency exit, and you need to open the secured door. No glass to break, no double button you need both hands for, and by the looks of it, not even a keyhole. So unless you have a working torch, you're fucked?
That just screams arbitrary puzzle. And if you can find a real world example of that, please petition to fix it.
I personally dodged the bullet by not buying Colonial Marines, and even though they are basically saying, "This is NOT Colonial marines," the mindset may still be there.
