Openers

Openers are builds for the first few minutes of the game. Their main priority is to be strong enough to hold off the opponents until you can determine what they intend to build, and push early so that you can focus on your economy. Some of the most common and powerful opening compositions will be covered on this page.

Please note that in the current form of the page that "->" will denote "then afterwards, build" or somesuch.

The page will be filled with situations for each build later.

Protoss
The primary Protoss openers are very strong early game but because they consist almost entirely of light units are easily countered by some of the Terran openers that rely on units that deal bonus damage to light. They are based mainly on the order and number of Sentries and Zealots. Common openers include:

Zealot -> Sentry

Sentry -> Sentry -> Zealot

Zealot -> Zealot -> Sentry

Terran
The primary Terran openers are quite simple and versatile for the beginning of the game. They're based around either early Marines or a single Marine followed by a unit that costs 100 minerals, or Reaper(s) followed by teching to heavier units.

Reaper -> Marine

Reaper -> One to three more Reapers -> Marine -> Tech

Double Marine

Marine -> Hellion

Marine -> Firebat

Marine -> Marauder

Zerg
The primary Zerg openers start with a single Zergling. Although you may see many players open with two Zerglings, they are so easily countered that you will want to consider using them primarily to tech up rather than making them for the purposes of pushing. They include:

Zergling -> Roach -> Roach -> Hydralisk

Zergling -> Roach -> Hydralisk

Zergling -> Roach -> Roach -> Queen

Mixed
Mixed openers are a bit different and this section is redundant. It will be folded into the primary racial openers at a later time. They are more advanced in idea but still simple enough for all players of Nexus Wars to pull off. Most of them center around using some of the strongest early game units, like Sentries, Zealots, and Firebats, to prolong an early push or hold against enemies so that you can focus on economy. They include:

Zealot/Sentry -> Zergling -> Roach

Marine -> Firebat -> Race Switch

Sentry -> Marine -> (Hellion/Firebat/Marauder)

One to four Reapers -> Race of choice. Most often seen used before a switch to heavy Protoss units, such as Archons or Immortals.
