It's free, and it takes up hardly any space on your computer, so it won't be an issue if you decide to install it.
But honestly, it doesn't make any sense. Why is Nihilanth there? Didn't Freeman kill it? OR Won't he kill it in the future? That REALLY got me confused. I get that it's a mod not a full game, but still, very poor. Nothing is ever explained is my point.

Not to mention the gameplay time. Just over 8 minutes. I'm sure that if I replay it now, I could be done with the game within 2-3 minutes.
