Thats what I was thinking when I was writing it 
But there would be two terminals to hack and the team of snipers wouldnt know where they were doing it.. so they could be all lined up waiting for the shot and the hacker could be at the other place 
Also the snipers can only chose between a dsr or a ballista, both bolt action On top of that the hacker would have 300-500% health
Thanks for reading and replying
