Halo Wars

Halo Wars Achievements

One and Done

Score the winning point in a game of Keepaway against Legendary AIs.

This is best done on the 1 vs 1 map Chasms. Use the Arbiter for this one. Set the AI to Legendary, of course, and have Captain Cutter be your opponent.

As soon as the game starts, build a temple and three supply pads. Scout with your Ghost for supplies, there are a lot near your base, and about 60 to 90 supplies in the center; collect those with your Ghost and move the Arbiter to the center of the map and wait. While you wait you can build a fourth supply pad, there is no need to upgrade to a Citadel.

By the time the Sentinel spawns (the flag), you can almost instantly grab it with Arby. Grab it and go camp at the back of your base, and wait. You will notice a timer running, that is how long it will actually take for capture the flag completely and have a point added to your score. You need three points to win.

Upgrade one of your supply pads every now and then, in case Arby needs to get into rage mode, but personally I never had to do this.

Now, when the timer has passed and you are rewarded a point, go back to the middle with Arby. Give him the upgrades ''Fiendish Return'' and '"Defiant Rage'' if needed, found at your Temple, and wait for the Sentinel and capture it, again camping at the back of your base. Repeat one more time.

Cutter will almost never send his units to you, he will be too busy building up his base. But if you really really want to be sure, listen to the AI about what kind of units Cutter makes, and build two turrets at the front to counter appropriately.

You will be rewarded the achievement after three Sentinel captures.

Not really much to say on this one.
Start a 1v1 game, I choose Blood river, as I know this one quite well.
What I did to make things easier was to activate all positive skulls, then make sure to get in the air as quick as possible. Acquiring a second base and get loads of resources going helped as well.
In the end you will get the achievement once you win the game. (Capture the 3rd flag)

Not that difficult indeed, just make sure you have enough warthog/hornets to capture the flag. Keep your base well defended and bring the flag carrier to the back of your base.
This worked for me.

This one was very difficult. I managed to get this by using The Captain as Leader and arbiter as enemy, then immediately build a reactor and then all supply pads, then in Memorial Basin there was an empty base on my right so i captured that and built supply pads while always using my scout warthog to get the flags. Eventually i upgraded turrets to flame mortar and warthogs to guass cannon, and build tons of warthogs, eventually they can withstand the enemy. The second base was useful as they would often attack it and leave my main base to continue production and provide cover for the flag carrier. Eventually using this method i was awarded with a bleep bloop. Hope this helps.

Start a 1v1 match on Exile with opponent as Arbiter and yourself as Anders. Activate all skulls in your favor. Build supply pads as fast as you can, then start pumping out Warthogs and Spartans. Let the AI grab the first 2 flags. Train some marines and have them take the 2 reactors nearest to you. Grab the base closest to you, upgrade it to a fortress and build an air pad. Start grabbing other bases and build supply pads but focus on getting hornets out now. when the flag appears again, grab it with the hornet and bring it behind your main base while your army guards the front.
It's annoying, the AI will press his attacks, but it will focus more on troops and gaining bases then pursuing the flag.
