Someone told that deadbeat's army stays there but if my memo is working right then i will say no to this...In terminator that is true but in assasin games, deadbeat's army turns out to be naturals....
What happens to the player whose target gets deadbeat. Easy the player gets new target which was the target of the deadbeat one. There is not a circumstance to happen in which two player have 1 target. There is a cirle mechanism, and everyone is set to be target to the player who stands at the couter clock wise neighboorhood. If one gets deadbeat, then cirle gets not very affected from it, simply the one who gets deadbeat drops down and your new target becomes the one who stands in the 2nd order neihgboorhood of yourself in the counterclockwise direction...
(counterclockwise or clockwise x no matter which one is)
I hope this helps, feel free to ask any further points which you find them to be still unclear to you

Deadbeat happens within 3 consequetive untaken turns, and in most cases a player is unable to kill his opponent in 3 turns...So it is a good idea to be cautious and to keep it in mind that your target might go deadbeat then better dont fully attack to your target in the very first turn. Dont run out your whole power...If he deadbeats before you finish him off, then you will have his target instead him and sadly your new target will be powerfull and wellgrown just because he was the deadbeat's target and because deadbeat didnt take turn and didnt attack to him.... This is a sad and weak point that we all confronted sometimes...Bothers a bit...
