So, what I have coming in a later patch is a new room and completely revamped AI for the Virus(s). In the past the virus(s) just made its way to the player without obeying the laws of physics (going through walls) Now the virus(s) know the layout of the map and choose the quickest way to get to you without going through walls.

Also if anyone has a suggestion or something they think I should add, please post it here :D
