How to unlock the You're so dead, you don't even know it achievement in Zombie Army Trilogy - Definitive Guide
Choose "Cadet" skill, and choose the "Zombie amount" for 1 player and you can breeze through in a few minutes.
I would choose the first level of the first campaign, it's the easiest.
You have to be 4 players in the lobby and then start a game and play it till the end together to get the achievement.
- Attempt to join random campaign match
- If you success in joining, you will be immediately directed to a screen where you will see names of other players (on the right hand side). There are four rows, each player’s gamertag will be displayed in each row.
- if you see that all the rows has gamertag (that means there are four people including you), you are good to go. Try to finish the level and hope that nobody quitting out. Or if someone quit out, but new person join in to complete the group of four, you are still good. Complete the level for your achievement.
- However, if you see that there are less than four people (you see one or two blank rows without gamertag), you may drop out immediately or wait a little bit in case someone join in and complete a group of four.
Again the idea is to attempt to join a game that already has 3 people playing. It does not matter if you start from the lobby or in the middle of the game, as long as you are the fourth person to join, you will get the achievement. The other three who join earlier before you will not get the achievement.
Play co-op with 4 players with 4-player zombies on cadet. Use the boosting thread to find partners. You're best off setting the zombie count to 1-player and Cadet difficulty to make it easier and quicker to do a level.
*ONLINE REQUIRED*
For this you need to complete a level in the campaign with four players in co-op. All players need to be in the lobby before the game starts and still in the game when you finish the level. Late joiners or leavers will void the achievement. As public games tend to start too quickly you'll either need to pre-plan this with three other people or play a game and hope nobody leaves during the next map.
