Halo Wars 2 Walkthrough

7. Skirmish

Special achievements

Here I will touch on this game's five special achievements to be aware of. Four of them are meta achievements that you should be working on while completing the non-campaign portions of the game. The final one is a viral achievement that requires you to kill a unit owned by someone who has the achievement (or a dev, but that's far less likely).

The four meta achievements are concerning daily challenges. Daily challenges can be viewed from the game's main menu and typically revolves around playing or winning games in a certain game mode, or as a certain leader. There are daily and weekly challenges and as they change every day/week, I can't predict what they will be when you play, nor can I suggest optimal times to slot them into the rest of the walkthrough as a result.

To count as a game played, the game must either last at least 3 minutes or be won be destroying the enemy base. Resigning immediately does not count!

I would suggest checking your daily challenges before you start to work on the non-campaign portions of this walkthrough and slot them in as you see fit.

Completing all daily challenges on any single day will unlock:

The viral achievement can be unlocked whenever you like. Your boosting partner might already have it, saving you some time. If you need to find someone for it specifically and have had no luck with sessions or on the game's forums, you are welcome to message me (EmagDrolBot) and I will help you out.

Here is where we will unlock the remaining achievements in the base game. We'll start with the only one that must be done cooperatively. Select Skirmish from the main menu and create a Custom Match.

Open up Game Settings and change them as follows:

  • Player defeat on loss of HQ timer should be set down to 15
  • Starting supply should be set up to 9999
  • Starting energy should be set up to 9999
  • Fog of war should be off
  • The After Party skull should be enabled

The default map (Bedrock) works well for every Skirmish achievement you will do, including this one. Invite your friend and then go to Team Setup to add a second enemy AI. Set both AIs to be on the same team and set you and your partner to be on the same team and start the game. Enemy difficulty does not matter. Select whichever leader you want and start the game.

As soon as the game starts, use the multiple minibase slots that exist to abuse the After Party skull in the same way as you did during the campaign. Queue up a minibase, then immediately recycle it. Repeat until you have an army of Scorpions or Wraiths and then swarm the enemy. Your partner should do the same with the other enemy. Winning will now be a pushover. I would suggest building on every base/minibase after you have your tank army complete, to prevent the AI building there while you destroy them.

Make sure to spend any Leader Points you start with or earn during the game and if you have a Leader Power that heals, use it.

Once you win, you will unlock:

Two heads are better than none in Halo Wars 2
Win a Skirmish match with a friend against only AI opponents (2 or more)
  • Unlocked by 10,407 tracked gamers (17% - TA Ratio = 2.41) 60,573

Next, you will complete two achievements that must be done solo.

Set up the game in exactly the same manner as before, except with only one enemy AI and with the AI difficulty set to Legendary. Once in game, proceed in exactly the same manner, but make absolutely sure to also recycle your own main base as well. Swarm the enemy to win and you will unlock:

Natural intelligence in Halo Wars 2
Play a Skirmish match alone against only AI opponents (1 or more)
  • Unlocked by 22,833 tracked gamers (38% - TA Ratio = 1.62) 60,573

You've got a case of the Birley in Halo Wars 2
In a 1v1 Skirmish against Legendary AI, recycle your base in the first 5 minutes and then win
  • Unlocked by 3,970 tracked gamers (7% - TA Ratio = 3.90) 60,573

Every one of the remaining achievements can be done solo, but some may be faster with a partner. Wherever this is the case, it will be noted.

Next, you want to train one of every UNSC unit and one of every Banished unit. This requires playing as all six leaders, since each one has access to some at least one unique unit. The games don't need to be played out though and you can resign after building your units in each case. In all cases use the same setup as you did for the Skirmish win achievements, starting with 9999 resources and no fog of war.

Start with UNSC units and select Anders as your leader. We will use her to train the bulk of the units necessary. You don't need to bother building any resource generators, but do need to upgrade your base to level 3. For Anders you need to earn at least one Leader Point in order to buy the ability to train Protector Sentinels. Spend your first one on Restoration Drones (and use them), then take your starting Marines out to farm the Sentinels that are around each Power Node and capture the nodes. This should earn you a second Leader Point.

In this game, you should build the following units at the following buildings. Unless you can kill your units off on the enemy base, you'll need to upgrade your population cap for this or alternatively leave out some generic units and build them with one of the next leaders:

  • Base units: Marines, Jackrabbit, Protector Sentinel (requires unlock via Leader Power)
  • Barracks units: Hellbringers, Sniper, Cyclops
  • Garage units: Warthog, Wolverine, Kodiak, Scorpion
  • Airpad units: Hornet, Nightingale, Vulture
  • Armory units: Douglas-042, Condor Gunship

Once you have built all that you can immediately resign and move on to the next two leaders. With Isabel, your only unit to build is Alice-130 from the Armory. With Cutter you should build Jerome-092, also at the Armory.

Recruit or construct 1 of each UNSC unit in Multiplayer or Skirmish (Launch units only)
  • Unlocked by 9,330 tracked gamers (15% - TA Ratio = 2.54) 60,573

Next, we will repeat the process with the Banished. There is no Banished equivalent to the Protector Sentinel thankfully, so you don't need to bother with farming Leader Points. Start with Atriox and build the following units. Once again, you will need to upgrade your population, lose some units to the enemy or leave some generic units to be built with the next leader. Just note that the Chopper is not generic!:

  • Base units: Chopper, Grunt Squad
  • Raid camp units: Jump Pack Brutes, Suicide Grunts, Elite Rangers, Hunters
  • Foundry units: Marauder, Reaver, Locust, Wraith
  • Apex units: Engineer, Banshee, Shroud, Blisterback
  • War Council units: Atriox's Chosen, Scarab

Next, select Decimus and build a Warlord from the War Council. Finally, select Shipmaster and build an Honor Guard from the War Council and a Ghost from the base.

The next three achievements all revolves around destroying 100 enemy units with their counter unit. All three are considerably easier with a boosting partner. If you have a partner, you can set up a Skirmish game in the way you should now be used to and train units for the other to kill. Here are the units you should use and the units you should kill in each case.

  • Use Wolverines or Reavers to kill Engineers. Reavers are suggested since you can both play Banished this way.
  • Use Cyclops or Hunters to kill Jackrabbits or Ghosts. If you want to use the same lobby as the previous achievement, you should both play Shipmaster.
  • Use Snipers or Elite Rangers to kill Marines or Grunt Squads.

If you are unable to find a partner for this achievement, then here are the alternatives.

For destroying air units with anti-air, the Sentinels you find around Power Nodes in Skirmish Deathmatches count. Destroy all of these using Wolverines, then resign and restart the game.

For the other two, you should create a Strongholds game. Set the time limit to 30 minutes and the additional population per Stronghold to 15. Set the rest of the settings (fog of war, etc.) to the standard boosting setup you've been using. In Strongholds, you do not upgrade your base with tech but are instead progressively granted access to better units. You also gain more population cap for owning more bases. At the start of the game immediately build on every base slot. Next, you should build as many of the unit type you are using (either anti-vehicle or anti-infantry) as you can fit alongside a few Nightingales then camp outside the enemy base. There is no guarantee they will build the unit types you want all the time, but they should build them some of the time.

  • Unlocked by 8,866 tracked gamers (15% - TA Ratio = 2.61) 60,573

All three of the final achievements involve actions that you will naturally undertake while completing the DLC, with the exception of Operation: Spearbreaker. If you intend to complete any of the Leader Packs or Awakening the Nightmare, then do those first and you will shorten this next section a little.

Our next goal is to destroy 500 units with Leader Powers. Once again, this is easier with a partner.

If using a partner, create a Strongholds game with the usual settings. Select Atriox for each of you and share the base plots out between you. Let the game naturally progress until you have some damaging Leader Powers. For the rest of the game, continuously build Suicide Grunts and gather them up. Use damaging Leader Powers on each other's groups of Suicide Grunts to kill them. Repeat until the achievement unlocks.

If solo, create a Strongholds game with the usual settings. Select Anders and build on all base plots before the AI does. Set a global rally point in front of the enemy base and build a bunch of Marines to keep them trapped. Wait until you are able to use the Retriever Sentinel Leader Power then do so. From this point on, let it sit in front of the enemy base and kill anything that comes out. Any kills it gets will count towards the achievement. Park a bunch of Nightingales on it so it doesn't die and consider having a small number of other units to kill any enemies that do sneak out and harass your other bases. It may take more than one 30 minute game to complete the achievement this way.

Finally, you have one achievement that you probably have already unlocked at some point on this page, and two very boring achievements. If you haven't yet unlocked Spare change, you will unlock it here.

Start a Skirmish game as Anders, buy Restoration Drones with your starting Leader Point. Use it, then resign. Repeat this process until you unlock:
