Infestors

Infestors are an interesting SC2 unit.  I have seen people do some pretty ridiculous "sneak attacks" with them I'll explain below, but as a whole I think this unit is drastically underused and is invaluable in tipping the tide in Zerg's favor.  I'll break this down by skill and what it dominates:

Fungal Growth
I could write a novel about this skill alone but that wouldn't be the most interesting read.  Over an 8 second time span, this 75 energy 9 range gem stops the army in the tracks as well!  For this "stopping" effect along it is invaluable for catching units in transition, especially air units like medivacs on their way to harass.  It is much more effective against biological terran units than it is against the shield heavy protoss.  Many zerg players complain of having no solution to the "bio ball" that is 3M (Marine, Marauder, Medivac), but make no mistake, fungal growth is the solution.  Cast and BACK UP letting the full damage take place and clean up with whatever troops you may have.  Similar tactic can be used to tip a ZvZ battle in your favor.  Did mention this comes standard on all infestors, no upgrade needed...

Neural Parasite
I myself am not the biggest fan of this spell, and since the beta has been over it doesn't get used all that often but this is a temporary mind control for all you SC BW fans.  For 100 energy, you control the other unit so long as your infestor does not die or move out of range of the unit.  You cannot burrow and use this ability (same for fungal above) so while controlling you are fairly vulnerable to attacks.  I find it better to use this against an early rush when there are fewer troops to kill infestors.  This of course is hard to do given the late acquiring of the tech.  Target tanks, thors, and collosi and start attacking their own troops as soon as you gain control.  Hopefully you can splash around some damage and make this worth it.  IMO, throwing a fungal down and backing up will do far more damage...

Infested Terrans
A fun little parlor trick I have seen (but have not successfully carried out myself) is to get infestors with burrow and infested terrans, burrow a large group of 6-8 into an enemy base, and spawn a slew of infested terrans to cause harassment.  If they have no detectors (at the stage you get them, most non-zerg players will, some zerg have been moving towards the overseer sooner but still rare imo) it can decimate economy and target tech.  I find these far more useful to intercept air troops on the move in conjunction with fungal growth.  Spawn 6-8 terrans and then lay down the fungal to make quick work of low hp troops.


Swarm on!
