Try to sneak past android multiple times without using any weapons because I'm stubborn, get past the first guy many times but get caught later or he chases me.
"Okay, I guess they want me to try out the EMP grenade"
I use it and it works, fantastic. I'll just stroll right by him and- ALIEN OUTTA NOWHERE.
The Alien NEVER once attacked me any other time. Was this just incredibly bad luck, or is this just a cheap scripted moment? This part actually made me feel quite disappointed. Why would the Alien only attack when I used the EMP grenade as opposed to running past or sneaking past by hiding?
EDIT: Ahhhh now I see what was happening. That's actually kind of clever, although still confusing... The alien was there the whole time, but for some reason ignored me unless I walked under a very specific spot. Pffft, some 'Perfect Lifeform'.
