lol... what a slowpoke i was... hey guys, there's a mission where i'm required to collect 6k of mineral to buy over mira han. how to pass that mission ha?

sounds rather difficult. if i don train units, i'll get harassed. if i develop, i don hav enuf resources.
hehe. imagine you play hard mode requirement is NOT build any SCV until you acquire the contract (which is, reaching 6k).
you play what mode i donno la so i gonna assume normal mode.
here's what i do

spam SCV for a bit. then get about 5 marines, 2 medics and 4 vultures.
with those units, go to the base north side of the map. whack all the SCV and command center.
while you're doing that, remember to build a bunker at the south gate, put 2 - 3 marines there just in case.
once your done, go to whack the base on the south side (by now you should have more marines, vultures and medics), this time you build bunker on the north gate with a few units around. put more units la. it's better.
once you settle those 2 command center, there's 1 left which is around the center.
regroup your team, make more units. then go whack. don't need to mass actually. just careful attack works just fine.
use spider mine, they're helpful.
in hard mode it's pretty much the same process, just you don't build any SCV until you reach 6k minerals. and oh, pick up the minerals from all over the place. it'll help a lot.
the harder the mode, the faster Orlan gathers minerals and the stronger the harassing forces.
the idea is to strike balance with training units and gathering resources.
if you one shot spam 5 marines, you lose 250 minerals. no point. just put 1 marine and 1 scv first. then only you go queue the rest. if got enough resources, can even upgrade with engineering bay.
