Starcraft 2 Best Co Op Commanders

Mercenary Leader and Dominion Admiral

Starcraft 2 Co-op Commander Guide Han Horner. Given their high price, the best way to keep them safe is to add some of Han's units into the mix. Additionally, these players will also find that they end up floating a lot of resources, particularly minerals as a result, because of the cooldown-based mechanic behind summoning Horner's units.

Sub-Ascension Leveling

Difficulty: Moderate

During early stages of leveling, Han's units are very fragile. However, rushing up to Horner's units will leave you extremely vulnerable in the early game. Therefore, start off with some of Han's units (with Death Effect upgrades researched) and transition into Horner's units as quickly as reasonably possible. To increase effectiveness in the early levels, use Mag-Mines aggressively, by placing them behind your army, just before you push in. You can lure enemy units into the mines to deal damage.

While leveling through Mastery levels, allocate points into Power Set 3 in a 2:1 split for the Air Fleet to Mag Mine masteries.

Masteries

Below are the three Power Sets for Han & Horner with the recommended point allocations for each. Note that these are meant to serve a general, all-purpose build that is effective across all maps with no Prestiges selected. You are highly encourged to change these masteries to suit your playstyle and particular challenges you face (e.g. Weekly Mutations).

Power Set 1:

Starcraft 2 Best Co-op Commander

PowerValueRecommended Points to AddFurther Considerations
Strike Fighter Area of Effect1% per point
30% maximum
?The death effects of Han's units can be fairly powerful when used correctly. Additionally, many players use Strike Fighters to take out single targets. These factors will go into determining how you set up your mastery points.
Stronger Death Chance2% per point
60% maximum
?

Stronger Death Chance is useful if you intend on using Reapers and Hellions (which have good Stronger Deaths). However, if you intend on using Strike Fighters, the Strike Fighter Area mastery is better.

Power Set 2:

PowerValueRecommended Points to AddFurther Considerations
Significant Other Bonuses0.5% per point
15% maximum
30The Salvage mastery can be useful for players that lose a lot of units throughout the game. It also benefits allies, and allows them to take greater risks with their armies by reducing the cost of losses.
Double Salvage Chance2% per point
60% maximum
0

The Double Salvage Chance is only useful if players lose a lot of units, which should not be the case for efficient play.

Power Set 3:

PowerValueRecommended Points to AddFurther Considerations
Air Fleet Travel Distance2% per point
60% maximum
20It is generally recommended to split points between these two masteries. The exact split depends on how aggressively mines are used, or what the intent of the Air Fleet is (to completely clear, or just weaken).
Mag Mine Charges, Cooldown and Arming Time-1% per point
-30% maximum
10

It is useful to have a higher Mag Mine Charge cap than is provided. Your playstyle will determine how many more you'd like to add.

Prestiges

Below are the prestiges for Han & Horner. Note that 'Effective Level' is the level at which the prestige achieves it full effect.

LevelNameDescriptionEffective LevelNotes
1Chaotic Power Couple
  • Advantages:
    • Mag Mines arm and fire 80% faster.
    • Mira's units' on-death effects are 100% more effective.
  • Disadvantages:
    • Horner's units cost 30% more.
1None
The increase in the arming speed of the Mag-mines makes this prestige very useful when trying to push into enemy bases, as enemy units usually do not have time to deal with the mines before they become invulnerable. Additionally since Horner's units aren't meant to be massed, but rather provide a strong backbone of support for Han's units, the increase in cost (albeit significant) is worth the benefits of this prestige.

Effectiveness Bonuses:

  • Reaper Mine damage increased by 5
  • Hellion Stim effects doubled
  • Hellbat Fear duration increased by 3 seconds
  • Widow Mine Sentinel Missile damage increased by 10

LevelNameDescriptionEffective LevelNotes
2Wing Commanders
  • Advantages:
    • Horner's units' vespene gas costs reduced by 20% and charge cooldowns reduced by 50%.
  • Disadvantages:
    • Galleons are capped at 2.
1None
This prestige provides players with the opportunity to mass Horner's units. However, the capping of Galleons at 2 is a significant detriment to the player's earlygame performance, due to the difficulty in being able to rebuild a lost Han army.

LevelNameDescriptionEffective LevelNotes
3Galactic Gunrunners
  • Advantages:
    • Bombing Platforms are no longer capped.
  • Disadvantages:
    • Bombing Platforms cost 100% more.
13None
This prestige might appear to be extremely powerful, but the increase in the cost of the platforms signficantly slows down a player's ability to build them. Considering that the player will also want to push (since Strike Fighters aren't effective against most mission objectives), and that the platforms can only deal with ground targets, the prestige is not very effective in providing the player with a useful benefit.

For general play, Chaotic Power Couple offers a good tradeoff between its advantages and disadvantages by allowing the player to use Mag-mines a lot more aggressively and also improving the death effects of Han's units, while still keeping Horner's units viable.

Recommended Army Composition

The recommended army composition for Han/Horner is below. Note that this assumes no Prestige talent selected and recommended Mastery Allocations. This is a basic recommendation for your army framework. It is recommended to gain an understanding for each of the units in the Units section and further add tech units so that you are able to better handle the situations you face.

Reapers should be making up the bulk of your army with Hellions to provide the death effect stim buffs. Additionally, Ravens should also be added in to provide extra damage bonus to Reaper targets.

If you have access to enemy spawn compositions, you may use Widow Mines to spawn-camp those locations and further reduce damage taken by your army.

Gameplay Guide

Playstyle Traps

A common trap for Han & Horner players is completely skip on Han's units in favor of Horner's more powerful air units. This can be quite an expensive mistake, as Horner's units, while strong, cannot take prolonged lengths of damage. This is particular true for the Asteria Wraiths, which naturally draw a lot of aggro. Given their high price, the best way to keep them safe is to add some of Han's units into the mix.

Additionally, these players will also find that they end up floating a lot of resources, particularly minerals as a result, because of the cooldown-based mechanic behind summoning Horner's units. Thus, it is better to use these spare resources to your advantage by making some of Han's units.

Playstyle Tips

  • Place Mag Mines on enemy spawn points to destroy attack waves.
  • Take advantage of the death effects of Han's units.
  • Careful placement of Precision Strike targets can help you weaken enemy forces. On maps like Dead of Night you can sometimes hit three buildings with one strike.
  • Build a Supply Depot in front of Mag Mines to draw enemy aggro and keep them still while the Mag Mines trigger.
  • Contrary to the description, Space Station Reallocation does not instantly destroy every non-heroic unit/structure. It deals a total of 5,000 damage to everything it hits.
  • Space Station Reallocation does reduced damage to some non-heroic structures. For example, Zenith Stones on Temple of the Past do not get instantly destroyed by the calldown, despite having no Heroic tag.

Starcraft II is a real-time strategy game by Blizzard Entertainment. It is one of the most successful RTS's in history. In 2015, Starcraft II introduced a co-op mode, where two players would face up against Amon in a PVE-type mission. The game features several different commanders to play and many different maps to choose from.

This site serves as a repository of all the information gathered by the Starcraft II co-op community. It aims to help players improve their gameplay, by providing in-depth commander and map analysis, as well as providing tips on how to deal with certain tricky situations that may arise in-game.

Starcraft II is currently free to play. Three of the commanders in co-op mode are free, while the others are free to play up to level 5. If you are a new player, check out the New Players page to help you select your first commander. Also, check out the General Tips page for some great tips to get you started with this game mode.
