When you go to select this dreadful mode. it comes up with the following:
"Survive enemy shades"
So, what does this mean?
Is it an American "slang"?
Another trolling method?
It's like saying "survive enemy Lazarevic"
Either way... You know. Eh.
It's pretty self-explanatory...
Survive (don't die)
Enemy (your opposition)
Shades (what your opposition is)
By the looks of it, it sounds like you're confused as to why shades is plural. Well you fight multiple shades in the mode, not just one. Shades are a group not a person.
Also it's already solved, so...
