how do u beat Left 2 Die Brutal before 5th night?? - Page 3

-> 2 bunkers at every entrance; one bunker on both downside highgrounds + 1 - 2 turrets there
-> 1 bunker + 2 turrets at mineral lines
-> 3 rax (2 reactor 1 techlab [stim!])
-> mass marine + few medics + call down goliaths as spotter defense
(optional: reinforced bunkers/tanks)
-> use your mobil force to kill chokers
-> get bunkers on top and bottom up in time (2nd night mineral line harass; 3rd night top breaks down; 4th night bottom breaks down)
-> constantely produce marines/medics
-> clear the map with stim
-> bio attack upgrades don't hurt either

-> use your barracks and your factory to wall off the front asap(ai will focus bunker exception are all special types but that can be dealt with)
-> 2 bunkers on the lowground in the beginning with sufficient repair
-> then bunkers on the highground + turrets
-> 2 bunkers at your mineral line
-> reinforced bunker upgrade recommended (also the building armour and the turret range)
-> 3 rax (2 reactor 1 techlab [stim!])
-> bio attack upgrades don't hurt either
-> tanks as early as possible same with goliaths
-> produce marines/medics non stop
-> the skank must be dealt with with micro (if there is any - i don't remember; stim kiting works fairly well)
IMPORTANT: the nydus worms (plural!) will spawn at random locations but can all be hit with tanks positioned in the mid of the base -> FOCUS THE NYDUS AND THE NYDUS ONLY (if you don't bring it down within 10 seconds you are breached and there will be no Gandalf to save the day)

the 14th wave will most likely breach your defenses no matter what you do but do not despond despite your entire people dying a horrible horrible death you will get your achievement.
