Today I am going to discuss one little-known
and frequently underused strategies in Starcraft
2: picking the right unit upgrades.
This simple mistake can actually cost you a lot
of games and you would be surprised how many
players are actually making it! After all, by default
only 20% of the player-base gets to be in the
Diamond League!
What I am referring to is picking the right upgrades,
both armor, weapon, and research upgrades. It
turns out that depending on which race you are
playing, your upgrades should change on a game-
by-game basis.
For example, did you know that it takes 3 attacks
for a Zealot to kill a Zergling, but if the Zealot has a
+1 weapons upgrade, a Zealot kills a Zergling in 2
hits?
A Zealot normally deals 16 damage a swing, and a
Zergling has 35 health. After two swings, a Zealot
would normally deal 32 damage. This is not enough
to kill the Zergling.
However, with +1 to weapons, Zealots deal 18
damage a swing and will end up dealing 36
damage and killing the Zergling in two hits! This
is like a 50% damage upgrade for your Zealot.
Likewise, a Zerg player could upgrade Zerg armor
and allow his Zergling to survive once again for
3 hits versus a Zealot.
There are a few specific instances of this. Here
are some notable examples:
- A Siege tank in Siege Mode with +1 weapons
will kill a Marine with Combat Shield in 1 hit. This
allows a single Siege Tank + a few Missile Turrets
to defend an expansion from a Marine drop.
- A Hellion with the Pre-Ignitor upgrade will begin to
kill Drones and Probes in 2 hits.
- A Reaper or Ghost with +1 weapons will kill Drones
and Probes in 2 hits.
- A Thor with +1 ground weapons will kill a Roach in
2 hits (as opposed to 3).
In all these examples, getting +1 weapons makes a
huge difference to the actual amount of kills a unit
will get without actually changing its damage too
much.
There are quite a few examples of this. Take notice in
game of what you have and what your enemy has and
see if an upgrade would or would not be of benefit
for you.
Here are some general rules of thumb:
- Zerg should always focus on carapace upgrades for
ground units. This will give more flexibility if you want
or need to switch between Hydralisks, Roaches,
Zerglings, and/or Ultralisks. Upgrading each weapon
independently is not a great use of money.
- Protoss should almost always go for +ground
weapons. Most of their units seem to benefit
immensely from this, and unless you are going for
Void Rays, you will probably use ground as a
Protoss.
Additionally, +ground weapons adds bonus damage
to a ton of units: Zealots, Stalkers, Sentries, Immortals
and Colossi. A single upgrade rarely benefits so many
units.
- Terran players will almost always want to opt for
+vehicle weaponry as these units seem to benefit
immensely. +5 damage to the Siege Tank’s and
+6 damage to the Thor’s ground attack is a big
damage upgrade.
If you are using infantry as a Terran player, I
almost always opt for +weapons. This will allow
you not be negatively penalized for fighting very
high-armor targets like Ultralisks.
You should also look at other types of upgrades.
For example, in the original Starcraft, Psionic
Storm was one of the most powerful abilities in
the entire game.
In Starcraft 2, it is not as powerful, and in order to
get this ability, you will need to build a Templar
Archives, a High Templar, and research Psionic
Storm.
This is a large investment and this same amount
of resources would be better off spent adding
another 5 Sentries and 3 Zealots to your army.
Try to stay away from any unit-specific research
unless you plan on making a lot of use out of
that one unit.
Also, be sure to consider the cost of the building
that you are doing the research at. If you are
pulling off a Void Ray rush, don’t think of the
Void Ray +speed upgrade as costing 150 minerals
and 150 vespene gas.
You need to consider the cost of the Fleet Beacon
you will also need to build in order to research
this technology. This is an additional 300 minerals
and 200 vespene gas, which is very expensive!
You could buy 2 more Void Rays for the cost of
the building and upgrade. If you are rushing, more
Void Rays is likely to be better than +speed for a few
Void Rays.
And that’s all for today. Following these tips will
give you more money to spend on units and amass
the most powerful army.
Speaking of being efficient, making more units
with less resources is tomorrow’s topic and it
can seriously turn your game around.
Until next time,
