I set up and played out an Open War game, a simplified ruleset for 40K, to let a friend play out the first battle round in a 62 Power Level (around 1,200 points) game between a selection from my White Scars and my Talons of the Emperor force for Crusade play.
The mission we generated from the Open War deck for 9th edition was simple--kill as much as you can on the opposing side. There were no objectives. We did draw a Blinding Sun twist to the game, but promptly forgot about it once the dice started rolling.
My friend (who chose to play the Talons) had to go home after the first battle round, so I finished out the game on my own. The combined Custodes and Sisters of Silence force, not hampered by having to hold objectives, delivered a sound thrashing to the White Scars, who perhaps unwisely spent a turn focusing fire on a nigh-on invincible Shield-Captain who was not only -1 to hit, but also -1 to wound, had a Toughness of 5, a 2+ armor save that would ignore 1 point of Armor Piercing, a 3+ invulnerable save, a 6+ Feel No Pain rule to shrug off any wounds that did get through, and a bonus wound to his maximum on top of all that. Not one wound got through on said character in several rounds of shooting and combat.
I recorded one point of Requisition earned for either Crusade force, though no agendas or experience points were tracked for the game this time.
