A hefty update coming soon, fixes a lot of things that aren't bugs like load time.
For those who have problems loading the game just wait patiently and it should load in time, I am going to try my best to fix this and other types of things like that.
Another example: There are less enemies in Single Player but I can fix it to where there are even fewer so that the game is more enjoyable for people going solo.
Just fyi it's meant to be played with friends, it enhances the overall experience many times over. I did add an A.I. that follows you at the last minute and it's enjoyable too but nothing compares to the experiences you can have when playing with friends! It's a blast!
