How do you usually play? I mean build orders, capping orders, everything from the start. Of course every answer would have to be map dependant but look away from it this time.
I never have on usual build order, that is just plain ass boring. It depends on the map, if it is a small map I skip t1 and go double mg into double pio into double 222 into pgrens and see from there. If it is a bigger map like angoville, I get one mg followed by 3 grens, perhaps a mortar and then go t2 into one or 2 222 and a pgrens.
Unless the USF player makes a mistake, he can hold out until the first CalliOP and get lucky wipes with the sniping mortar.
