绝命六分

Time limit: 6:00 (Not shown)

Timer can't fall under 10:00 of the initial 15:00 or participants will not get credit. The six minutes appears to count the 60 second preparation window Assault knights respawn after 60 seconds if others are not defeated; therefore if going for the achievement, split between the three, burn as hard as possible and kill with 11:00 on the timer if possible, then help the other two groups.
