The bulkhead door explodes in a mess of molten shrapnel and plasma. Five assassins step out of the wreckage and start opening fire on the security guards. Lankton tries to take cover behind the guards.

Lankton manages to escape the bolt of plasma headed his way, but the guard he was hiding behind is less fortunate. He dissolves into a heap of melting, burning slag. The firefight continues, but fortunately Lankton's warning gave most of the civilians enough time to take over.
[Acrobatics: 50 + 16 - 32 vs d100 = 19 (Success)]
Lankton continues to avoid the plasma, diving for cover. Taking a glance at events in progress, it looks like things aren't going well for the assassins. Two of their number have already been shot down by security's conventional pistols. Seeing that things are failing, the remaining assassins back away through the door, vaporising their lost companions with plasma bursts. One of them, possibly the leader, takes one last shot at Lankton before departing.
[Rifle: 50 + 32 - 16 + 5 (circ bonus) vs d100 = 35 (Success)]
Lankton's luck couldn't last forever. While trying to move for more cover, a bolt of plasma sears across his back, burning away much of his skin and flesh.
[Lankton takes (2d6) 7 hp damage from Plasma fire - down to 1 hp.]
With the last hit managed, the assassins escape back the way they came. About this point, Ambassador Hackra arrives on the scene. Everyone on the station hears the alert, as well; "All traffic to and from the station has been halted until the terrorists are found."
