Dark Messiah of Might and Magic Elements

Multiplayer -> Player match -> Team deathmatch
No private slots.
5 minutes duration.
Remember that you need at least 8 players.

It's better to have in boosting team one person with this achievement - this person should be in opposite team. The rest of players may be in 'I need this achievement' team (1 vs 7).

Start your game, kill person(s) in opposite team, wait to the end of the match. Repeat 10 times.

If you don't have a player with achievement, play with your 7 boosters this way:

match - winning team (player no #) - loosing team (player no #)
match 01 - 1 2 3 4 5 6 7 - 8
match 02 - 2 3 4 5 6 7 8 - 1
match 03 - 3 4 5 6 7 8 1 - 2
match 04 - 4 5 6 7 8 1 2 - 3
match 05 - 5 6 7 8 1 2 3 - 4
match 06 - 6 7 8 1 2 3 4 - 5
match 07 - 7 8 1 2 3 4 5 - 6
match 08 - 8 1 2 3 4 5 6 - 7
match 09 - 1 2 3 4 5 6 7 - 8
match 10 - 2 3 4 5 6 7 8 - 1
match 11 - 3 4 5 6 7 8 1 - 2 - achievement for players: 3, 4, 5, 6, 7
macth 12 - 4 5 6 7 8 1 2 - 3 - achievement for players: 1, 2, 8

You need something about one hour to let everybody get the achievement. Thanks this method you dont't have to play 20 matches (10 for 7 players and 10 for a player from opposite team) and you can save 40 minutes.

"Most important thing to know about this achievement is that you have to play a match with NO private slots". You have to have everyone search for the game.
These can only be done in player matches.

Note: As of 2022, the Online Game Mode for this game is still working. But I would suggest you get the Online Achievements done for this game, sooner than later.
The Online for this game is Dead, so your going to need to Boost It. It is highly suggested that if you have Dummy Accounts & Extra Copies of the Game and Consoles, to bring them in as well.
This game is Not Backward Compatible on the other XBox Consoles. And the game has a bad habit of Freezing your Consoles on regular occasions.
Finally, it is recommended to install the game to your Hard-Drive if you are playing the game with a Retail Disc. It takes 6.8GB's.

You can do this Achievement either in Player Matches, or Ranked Matches. I would personally recommend "Player Matches", as it can be done more faster in this Game Mode.

You will need a minimum of 8 Players, to get the Achievement.

The fastest way in which you can get this Achievement is to choose someone to sacrifice themselves for the Team. Better yet, if any of you have a Dummy Account that can be used towards this Achievement, then that will be even better.

Assuming you want to do Player Matches, the Host needs to Create a Team Deathmatch, and a Map of their choice. Personally I recommend Deep Forest...

Now here is the difference towards Player Matches & Ranked Matches. In a Player Match, you can adjust how long the Match will be, giving you the lowest time possible, which is 5 Minutes. In a Ranked Match, you cannot change the Time Limit. And by Default that's 15 Minutes. Which isn't good... unless you wish to use this Game Mode to work on other Ranked Achievements.
With this in mind, I recommend changing the Time Limit for 5 Minutes (Player Matches). And then you can go ahead and Create the Match...

When the Match is created, get everyone to search for the Match and hope they can join it.

Now it's time for someone to be the Sacrifice or where the Dummy Account can be placed in. For everyone that's going for the Achievement, they need to put themselves on one Team (for instance, the Humans). If there's 8 of you in total, this means 7 People would be on one Team. The lonesome Player on their own needs to join the other Team (for instance, the Undead). It should all end up being 7 VS 1.

Note: I believe Ranked Matches do not allow you to have Un-Even Teams in the game. In this case, it would be 4 VS 4, and you will have to trade Wins to get the Achievement.

Once everyone has chosen their Classes & Ready Up. The Host can then press the button to Launch the Match.

Now when the Match begins, all that needs to be done is get one person on the Winning Team, to Kill the lonesome player at least once in the match. This is so that the Team that has 7 Players, are Winning against the lonesome Player. Otherwise the match will end in a Draw, and it will be a waste of time. Once that lonesome Player has been Killed at least once, everyone can stand around and wait idle until the match is complete.

Note: The rest of the Players can stand still and do nothing for the Match. But it is highly recommend that everyone who is wanting to get a Win towards the Achievement, that they move around for a short moment to get rid of the Invulnerability.
The reason being is because standing around for the whole Match, being inactive could possibly void you from getting a Win towards the Achievement. As a Priority, the lonesome Player on their Team & at least one player on the other Team need to move at least once to get rid of the Invulnerability, and claim a Kill. Otherwise if a Kill is not achieved, the match is a waste of time for everyone.

Once the Match has been completed, the Host will have the ability to Re-Host the Match with the same Game Mode, Time Limit and features. Rinse and repeat, until everyone get's the achievement. If you have to swap Teams to give everyone Wins. Make sure you do so after one respective Team, get's all of the Wins & the Achievement.

Note: You cannot Re-Host the Lobbies in-game during Ranked Matches. This only applies to Player Matches. If you do Ranked Matches, you will have to get everyone to back out and Leave. Then the Host needs to setup the whole match again and get everyone to research again.

As a side Note. If the Winning Player ends up being a Host, they will progress towards this achievement as well...



Tip: To reduce the amount of time, needed to get this Achievement as well. I suggest you Swap Hosts, rather than letting the same Host Win & Lose, all the Matches needed to do, towards the other respective Achievements your going for.

Hope all this helps. Good Luck.
