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.This Achievement has to be done in a Ranked Match.You will need 10 Players, to get the Achievement.
To get this Achievement. You need to successfully complete a Ranked Blitz Match in less than 8 Minutes. Whilst the other Solutions state you can get the Matches done by capturing the Flags as quickly as possible. There is another Method you can apply, which might be easier.
First you need to decide who is going to Host The Ranked Match...
They need to Create a Blitz Match on a Map of their choosing. Personally I would choose Deep Forest...
Now once the Lobby is Created, everyone then needs to search for it and hope they can successfully join...
Now here is the Important part towards this Method. As there are 10 of you in this Lobby. You need to split everyone in Half. So I suggest putting 5 of you on the Human Team. 5 of you on the Undead Team. At the same time. You need to decide who is going to Win or Lose. Whomever is Losing, needs to choose a Mage as their Class. Make sure they choose the Elemental as their Attack Formation. The Winning Team doesn't matter...
Once everyone has chosen their Teams & Characters & Ready Up. The Host can press the
button to Launch The Match...
OK, so for the Team that's Losing as the Mages, everyone needs to gather round and Jam Pack yourselves together. Like a Tin of Beans. This will also get rid of your Invulnerability for Idling. The next thing you need to do is have one of you press and hold the
button, then press it a couple more times to cause a Meteor Storm. This will damage the User & anyone surrounding them. It should Kill everyone on their Team and end the Round. Rinse and repeat until all 3 Rounds are done.
If for some unknown reason, someone on that Team is still alive from the Explosion, either get them to Kill themselves solely by making them look down and holding the
button. Or have someone on the winning side run over and quickly get a Kill.
Once all 3 Rounds are done. The Achievement should then Unlock. You may need to rinse and repeat the method for the Team that lost the Match as I'm not sure if you have to Win to get the Achievement to count.
Hope all this helps. Good Luck!
