With every steam sale we get another hand-to-hand combat or boarding or personal handguns thread, however none of this will ever happen for good reason, Muse has said that boarding or killing individual players is against there vision of a tactical game that's main gameplay is based on blimps fighting each other.
So we will never see any of this mainly because most people don't want it (where is the fun in a pilot doing a crazy maneuver only to be killed by 1 guy spraying a gatling, and if there is no medic than the pilot "dies")
