Okay no way I can do that in one turn. What do I need to advance under cover?
Or is it possible to do it in one turn?
You could do it in one turn, I think, with a -10 range penalty.
Of course, as they say "almost only counts in horse shoes and hand grenades", and as long as your projectile is within 4 meters of the target you're attempting to hit (which is likely), you should do at least some damage
There is a mechanic for cover in Rogue Trader, however in this particular maze we're in there isn't any cover other than the corners themselves.
Since you want a map: I'm basing the maze we're in on Pac-Man's Maze (simply because it's a robust design). Here's an image of that:
We're currently at that "r" shaped object right of Pac-Man's starting position. The big pellets are each one of the flags we need to grab.
The enemies are located north of us, at the bottom end of the sideways "T" shaped object.
Also, note that as your character is an Ork, running into fire is a fairly safe option here-you knock 8 damage off of
any attack.
