As I only have painted Space Marines, Chaos, Squats and Orks so far, I decided to run the campaign "Trouble in the frontier", using Space Marines as my personal retinue, Space Orks as main enemy and Chaos and Squats as secondary ones.
As usual, all pictures are clickable.
I have in my retinue one Librarian with the psyker power "Path of shadows", 1 devastator marine with missile launcher (as it does not exist in the weapons list, I chose rokkit launcha stats instead), and 4 Tactical Space Marines with Power Armour and Bolters.
I rolled "Whispers in the dark" in the investigative missions chart: A member of the Enemy camp wishes to come forward and offer assistance to your investigation. The informant (placed in the middle of the board) must be safely escorted off the board. If the player gets him off-table, he will earn 1 Victory pt.
Ork line racing forward
In the first turn both retinues run towards the objective in the centre of the board (the traitor, represented by a Chaos Sorcerer figure).
In the second turn the Librarian reached and captured the traitor. The Devastator shot and killed the 'Ard boy first, and then thanks to its Gun kata, he fired again and killed the Warboss! The rest of the Space Marines fired and got one Kommando KO.
The Ork Nob avenged his boss and killed the Devastator with his big shoota.
In the third turn the mauled Orks gained the initiative and advanced and fired, missing all shots. Marines started to fall back and missed all their firing as well.
In the fourth turn Marines gained the initiative again and kept retreating and firing, most of them taking cover in the ruins. The Ork Nob, using Torrent of fire, managed to kill another Marine, the one who did not get to the ruins!
In the next turn Marines moved first again and the Librarian and the traitor left the board, thus accomplishing the mission. The rest of the Marines kept moving back and shooting, this time killing one more Ork and leaving two of them KO.
The Tactical Space Marines behind cover, buying time for the Librarian to escape.
