So i figured out this method that has helped me so much that between waves of 1 and 15
im averaging as number 1 - 3 in scoring and kills when playing with 5 people (especially pros)..
ok so what you do is!!!
Play Horde on "Private", Difficulty on "Normal" with "Invite Only" selected so no one jumps in.
by doing this you are by yourself to set up defense and forts, you force yourself to learn the course,
and you learn ways to manuver better because your by yourself. by myself i have been able to
get better to where i can make it to wave 6 on my own. AND YES IT IS HARD TO DO!!! but if you can get that far by yourself just imagine now when you play horde with other fellow GOW3 players. you now stand a chance
of getting more than half a kill assist and spotting things for other players because your dead lol...
i hope this helps!!
