4. Halo 5: Forge (Win 10) Multiplayer Achievements

Now let’s start working on the achievements, that require additional people.

I'd advise you to get a group via a session, for three of them and to team up with a single person to knock out the rest together.

Once you found your partner to do the ones you can finish with two people, go to the bottom right of the main menu and to your friends, there you can invite him to a fireteam. After that’s done, go to "Forge" - "Build" and then load any Map. It'll put you and the friend in your fireteam into the map, where you both can forge together, unlocking:

Friendly Forging

Start a Forge session with another player.

Now go back to the main menu, "Forge" - "My Data" and select a map you created, if you followed the walkthrough, just choose the one we made in "Solo Achievements".

Here choose "Play custom game", the game mode should be Showdown, but if it isn't change it to that and change the properties of the game mode in the game mode options to "15 points to win" (10 would also be enough, but you need to get 7 headshots, so I set it to 15) and the spawn timer to 1s for convenience (at the respawn tab), also deactivate the visibility check (also at the respawn tab).

Now start the match and it will load the map for you and your partner.

Once the map has loaded and you both can play, you want to kill your friend 15 times without dying, make sure that at least 7 out of those 15 kills are headshots. After you reached 15 kills and won the match you will unlock three achievements for getting 7 headshots, winning with a 10+ kills/death ratio and by winning a 1v1 match on a map you authored, make sure to let your partner do the same to earn the both of you:

Hats Off

Back at the main menu, load up another one of your own or your partner’s maps. The game mode and everything else is not important. Just load up any custom game like in the previous step and make sure it’s a map one of you two authored. After it started and both of you can play, just press ESC and quit the match. If nobody got any kills it will be a draw and luckily for us, a draw counts as a win, too.

Do this a total of 25 times and both of you will get:

Nice Work Dawg!

Win 25 Custom Games.

There is also an achievement for doing this a total of 117 times, but as it requires you to just finish 117 matches and not win you can also do this solo. If you want to do it with you partner just continue the previous step until you both have it and if you want to do it solo, the same steps apply, just without inviting a friend to your fireteam in the first place.

After you did it 117 times, with a friend or solo you'll finally unlock:

Running Riot

Complete 117 Custom Games on player created maps.

Now off to the tricky part, where you need 7 other people. You need 3, 4 and 7 people respectively so it is smart to get 7 people and knock all of them out at once while you are at it and have a group going.

Once you have your group together make sure you add them all as a friend. Like all games that require Xbox Friends, its best to send the friend request via an Xbox 360 or the xbox.com website and not via the Xbox App or the Xbox One. The first achievement we're going to get is for being in a fireteam with three friends. This can be a little tricky to get to pop but here are three things you can try to get it:

  1. In the main menu invite 3 or more people to your fireteam and load up a custom game like you did before and quit it right away like if you want to do the wins in the other step.
  2. If it didn’t pop after you finished the game, try to invite only 3 people to your fireteam and do the same.
  3. If it still didn’t work out for you start a costume game by yourself without anyone in your fireteam and let the other people join you via their “friends” tab from the main menu. If it won’t unlock for someone let him host and repeat those 3 steps.

Everybody should now have:

Squad Goals

Be in a Fireteam of 4 or more.

In order to give everybody the last two achievement left, host a custom game on a map you made yourself, with 8 players. Just invite them to your fireteam and load up a custom game on YOUR OWN map like always. After this one everybody should unlock:

Community

Complete a Custom Game with 7 other players on a user created map.
