Theirs 2 ways you can approach this... 1 way is you give up and leave, trust me, this person has nothing to do and will be there for 4 hours holding you till he needs to eat, or sleep. the second way is to spam marines, and tanks, have the marines attack the front and the tanks on the back of his base.
Remember Tanks, marines, with the cyro and d bomb Will equal WIN! = )
The only way this works is by sending marines to the hook (if he has one) so he cant see the tanks, perfect micro, land uck that the player is not paying attention at the time.
if it doesn't work, you either did something wrong or he learnt how to counter that... because that's how i beat him.
Halo 3, 1 on 7... no challenge. If the connection is with me good luck winning.
Halo Wars on the other hand...not so much.
Who loves Halo...I do! =)
