Alien Question,,

[Killer Turnus]

So the aliens, they sneak in the base now i hear. is it right away or do you need to trigger the storyline?? and are the stalkers dangerous? or are they meant to scare the crap outa you? I havent experienced the game much cause i have alot of trouble on normal. my math is awful..

they cant hurt you, but the corner peeker is just a random event, and the window lurker is only seen at night. The one in the garage is one i've seen only thrice and i dont know how they spawn. you can find 2 more aliens once you do the spires out back behind the solar panels and there is a corpse somewhere on the tracks between dishes 8 and 13. they're just there to keep you alert. name them and then whine at them whenever they spook you.
