Bunker Buster Achievement

KI never builds bunkers in skirmish missions. Havent seen some in the campaign as far as i played it (not so far i admit).

How to farm it

Go to mission (challenge map): fortress siege

Just rush the left way up.
4 bunkers in this mission (red dots u see in the map).
Ur troops spawn endless.
Destroy those bunkers.
50:4=12,5
Play this mission 13 times ------------> Profit

And now go back to the rest of the freaking grindy achievos this game has.

Hey buddy, i always finished the mission to increase the total game count aswell for one of the other achievements. I'm not sure, but i think u can reset after killing the bunkers. Good luck with the achievo! :)

Do you have to finish the mission or can you reset on busting the bunkers?
