this replay will show you the basic spectre gameplay,
below ill list your upgrade order and a few tips as well as costs
ok so to be an effective support spectre you need atleast A 25G kickstart
spectre bases are non effective above titan level 4 so dont do em then.
your basic upgrade order will be phase 2 ops recon equip hercules,star light engines phase 3 and arc,i tend to put arc first depending on how far away gold is so i can get out some additional upgrades.
use your cargos to block paths when you run from the titan.
if you have the money on the ledge where i put war pigs a viable replacement is a spartan with 2 spectre towerrs on the side of the ledge behind it
you want 2-3 vultures for effictively fast spider mine laying though 2 will usually do i like to pump out a third
use war pigs to kill nydus worms and infested terrans.
if titan is chasing you,nade him straight away before he gets close and even block with cargo's.
never travel in the open without atleast 5 cargos if you can afford it.
unless its archon or infestor,if you have afew cargo's go ahead and be greedy just make sure you have nade up,remember spectre is very gold intensive late-mid game if your making things like spartans.
dont get upgrades you wont use,for example the vulture speed,unless your chasing down minis your not going to need it,save your gold for something else
war pig range up,this is subjective as it lowers your overall damage,you have to ask yourself whether you need the extra range and what your using your war pigs for,the armor pierce does help mitigate the damage loss however.
alright and that concludes this early spectre gameplay guide ill add more as questions are asked
