Okay, here's the start of combat then; it'll go as follows : first Alder'll rush in there, draw his lightsaber and move out (he catches them flat-footed, thus gains a move and weapon action.
That'll bring the bad guys into your position, from which you immediately can start to fire.
Then initiative will go to the thugs and then combat'll resolve like normal...
It's hard to find cover in a wide and open place like Blue Deck. There's a doorway leading to the cargo bay, which looks wide enough so it could carry a repulsor sled. Perhaps two people could each duck besides one part of the doorway. And the only remaining cover Alder & Surussk are able to spot is.l..a rather large exotic plant standing somewhere in the middle of Blue Deck. ((the plant looks like our earthly mangrove trees)) It might be a good cover for the rest of you.
That set-up should work, now only to decide who'll take place where.
[Allrighty, i need initiative rolls plz -> Alder automatically goes first with his action, he can describe the effect of course]
