Halo Wars 2 Walkthrough

11. DLC: Awakening the Nightmare: Misc.

Terminus Firefight

Terminus Firefight is a wave based defense game mode. Unlike Blitz Firefight, it uses standard basebuilding mechanics and not cards. It is an online game mode that can't be played offline and can be played either solo or cooperatively. You defend a central Terminus structure from waves of incoming enemies, using your units, as well as turrets and walls.

One achievement requires that you play in coop mode and several others are considerably easier that way too, so find yourself a partner! Everything can be unlocked on the Easy difficulty, but you must not make any other changes to the game setup. If you do, achievements will not unlock.

The leaders you choose do not really matter and are down to personal preference, but one of you must be a Banished leader and the other a UNSC leader. Once in game, you will build your army composition similarly to how you defeated most of the campaign. Build and fully upgrade as many air units (Hornets and Banshees) as you can, while keeping some healing units (Nightingales and Engineers) mixed in. You should also build your leader's hero unit from the Armory/War Council. Fully upgrade any turrets you build as Banished, while upgrading any you build as USNC to anti-infantry as these are the most likely units to give your air units trouble.

All waves in this game mode are random, so I am unable to give you wave by wave advice. You will face Banished, UNSC, and Flood units. If you are particularly unlucky, you might face waves and waves of anti-air units, making your mostly air unit army strategy somewhat less effective. This is not particularly likely, but it's worth being aware of.

Your aim is to pass wave 15 without the Terminus (the thing you're defending) taking any damage. If you get unlucky in the first few waves and face units that can easily rush past you (like air units), just restart.

Like in the campaign, you will get a line on the minimap indicating the route that the incoming enemies will take. Position your troops accordingly and do not split your troops up unnecessarily. As you defeat enemies and gain resources, you can push out from the starting area towards a minibase slot. Here, you can set up more defenses and turrets. I would not personally suggest pushing out further than the initial minibase slot, or your army can become too thinly spread.

As you pass waves 10, 15 (assuming your Terminus has not taken damage), 20, and 30, you will unlock their respective achievements.

There are two types of score in this game mode. Individual score and total score. The total score is the sum of your individual scores. Ideally, you both do roughly the same amount of work and have similar individual scores. In any case, you'll unlock individual score achievements during the game:

Terminus Defender in Halo Wars 2
Get an individual score of 500,000 (Terminus Firefight)
  • Unlocked by 4,924 tracked gamers (66% - TA Ratio = 2.07) 7,423

Get an individual score of 1,000,000 (Terminus Firefight)
  • Unlocked by 4,692 tracked gamers (63% - TA Ratio = 2.12) 7,423

The total score achievements, however, do not unlock during the game. They will only show up after you are defeated. Once you have passed 5,000,000 total score, you can let yourself be overrun and then these two achievements will unlock:

Terminus Teamwork in Halo Wars 2
Get an total score of 2,000,000 (Terminus Firefight)
  • Unlocked by 4,438 tracked gamers (60% - TA Ratio = 2.18) 7,423

Get an total score of 5,000,000 (Terminus Firefight)
  • Unlocked by 3,800 tracked gamers (51% - TA Ratio = 2.36) 7,423

The next achievements should be done solo and are all relatively quick and easy.

Start a game as whatever UNSC leader you want. This can be done as Banished as well, but I found that the starting UNSC troops are much stronger. Your goal is to pass wave 5 with your starting troops. Turrets are allowed, so you should build those (don't upgrade them). If you get unlucky and hit with a bad wave, just restart. Once you succeed, you'll unlock:

Survivor in Halo Wars 2
Survivor16 (5)
Finish wave 5 without training additional units (Terminus Firefight)
  • Unlocked by 2,100 tracked gamers (28% - TA Ratio = 3.17) 7,423

The rest of this game will be spent building and destroying turrets and walls. Defend using the same strategy as usual, but with two important differences.

  • Whenever you have the resources for it, destroy and rebuild turrets and walls. Don't bother to upgrade any of them.
  • Have a Hornet squad that you use to destroy supply drops. Optionally, send out a Warthog to grab the supplies.

The following achievements will unlock after doing this for long enough.

Ka-Ching! in Halo Wars 2
Ka-Ching!31 (10)
Destroy 20 bonus drops in a single game (Terminus Firefight)
  • Unlocked by 2,199 tracked gamers (30% - TA Ratio = 3.10) 7,423

Turret Farmer in Halo Wars 2
Build 50 turrets in a single game (Terminus Firefight)
  • Unlocked by 2,136 tracked gamers (29% - TA Ratio = 3.15) 7,423

High Maintenance in Halo Wars 2
Build 50 barricades in a single game (Terminus Firefight)
  • Unlocked by 2,263 tracked gamers (30% - TA Ratio = 3.06) 7,423

Resign that game and start a new one, this time as any Banished leader. Atriox works fine.

When the game starts, build a single Power Extractor, and then Harvesters with the rest of your resources. Defend until you can afford to build 2-3 turrets next to the Terminus, then split your starting troops into two groups and start to head out through the map, building on every available wall and minibase slot. Unstable Barrels only cost 100 supplies, while minibases cost 200, 300, or 400, depending on how far out they are. Continue to build extra Harvesters as well and upgrade them.

If you struggle to get both done in a single game, you can just do two games; one for walls and then one for minibases.

Build and hold a minibase on every slot of a map at the same time (Terminus Firefight)

Skirmish

The final six achievements are unlocked in Skirmish mode. Three are done as Voridus and three as Pavium.

Pavium's are considerably quicker and easier, so let's get those out of the way first.

Start a game of Strongholds with fog of war off, all beneficial skulls enabled and max resources. Once the game starts, build on every base slot and then build Mega Turrets in every slot once complete. Now you just need to wait for the Mega Turrets to kill enough enemies. It shouldn't take long. Build Pavium at the War Council, along with a few Engineers while this is happening.

The Long Game in Halo Wars 2
Kill 50 units with Mega Turrets (Multiplayer, Skirmish, or Blitz)
  • Unlocked by 3,618 tracked gamers (49% - TA Ratio = 2.42) 7,423

Pavium's next achievement can be done in the same game. Destroy all the Mega Turrets, then take Pavium and his Engineers and park them outside the enemy base. Use Pavium's ability and the Orbital Designator leader power on as many groups of enemy units as you can. Once you've hit a cumulative total of 30, the next achievement will unlock.

Marked for Death in Halo Wars 2
Paint units using Pavium or Orbital Designator 30 times (Multiplayer, Skirmish, or Blitz)
  • Unlocked by 4,367 tracked gamers (59% - TA Ratio = 2.20) 7,423

Finally, win the game by recycling all your bases to create Wraith tanks, then swarm the enemy. Do that in two more games and you'll get:

Unbreakable in Halo Wars 2
Win 3 matches as Pavium (Multiplayer, Skirmish or Blitz)
  • Unlocked by 3,047 tracked gamers (41% - TA Ratio = 2.63) 7,423

Our last three achievements are done using Voridus. They can be done solo or with a partner, but are considerably easier with a partner.

If you are playing with a partner, make a 1v1 Strongholds game with fog of war off, all beneficial skulls enabled and max resources. Each of you should create a mass of Grunt Squads and gather them up somewhere. Hit the other players group of Grunt Squads with Infusion Wake, then follow it up with Cataclysm to kill them all. After doing this a few times, you'll hit the 50 unit kill threshold.

Cataclysmic in Halo Wars 2
Kill 50 units with Cataclysm (Multiplayer, Skirmish, or Blitz)
  • Unlocked by 1,845 tracked gamers (25% - TA Ratio = 3.39) 7,423

Next, start a private game of Blitz against your partner. Both of you should create Voridus decks that contains the cards: Invigorating Frenzy and Infused Engineer. The rest can be whatever you want. Either capture a point each, leaving the third point alone, or just ignore the points entirely. Take turns collecting the energy drops.

Spawn a few Infused Engineers, then just cycle through your cards repeatedly until you hit Invigorating Frenzy. Use the Engineers' ability to drop Infusion on the ground, or you will not be able to use Invigorating Frenzy. After 50 uses, you'll get:

Revel in Destruction in Halo Wars 2
Use Invigorating Frenzy 50 times
  • Unlocked by 1,453 tracked gamers (20% - TA Ratio = 3.82) 7,423

If you are playing solo, you can do both of these in Strongholds, but it takes more than one full 30-minute game. Start a game with 15 extra population per base, 30-minute duration, all beneficial skulls, fog of war off, and max resources.

You now just need to wait outside the enemy base and repeatedly use any method of spreading Infusion over enemies (Infusion Wake, Voridus himself, Infused units), then Invigorating Frenzy and Cataclysm. You'll unlock Cataclysmic before Revel in Destruction, but they will both take a while.

Cataclysmic in Halo Wars 2
Kill 50 units with Cataclysm (Multiplayer, Skirmish, or Blitz)
  • Unlocked by 1,845 tracked gamers (25% - TA Ratio = 3.39) 7,423

Revel in Destruction in Halo Wars 2
Use Invigorating Frenzy 50 times
  • Unlocked by 1,453 tracked gamers (20% - TA Ratio = 3.82) 7,423

Finally, use the After Party skull to Wraith swarm your enemy three times in Skirmish to unlock:

Spreading Darkness in Halo Wars 2
Win 3 matches as Voridus (Multiplayer, Skirmish or Blitz)
  • Unlocked by 2,507 tracked gamers (34% - TA Ratio = 2.91) 7,423
