I just had an idea about what would make the Stalker type enemies more difficult.
The main problem with these types is that they act like any other unit and just stand there shooting at you, but can you imagine if they were controlled by REAL people. Like if they made it some secret rare side mission where your frame has been taken over and then sent out to kill your fellow Tenno. Or just some DEVs controlling them.
I don't know...just an idea.
tell me what you think.
