last night ultramarines attempted to bait out the loxosceles remnants in a decisive engagement .
1000 points. We played this neat scenario in the middle of a warp storm which made all deep strikes downgraded to strat reserves. Unless you completed a shoot signal flair action- in which case you could deepstrike near the unit which completed it.
And every unit had infiltrators, but demons spawned around the portal in the middle.

The ultramarines did succeed in bringing loxosceles to battle, but loxosceles struck the marines as they fought several fried synapse nids(demons) which were thrown out of the warp , disorientated and feral.
What followed was a dark day for the chapter.

Loxosceles victory: 1 req spent to use 3 agendas. 3/3 agendas achieved
Destroy up to 5 marked units in melee - 3/5
Kill general - achieved
Devour all biomass - achieved.

Here’s deployment. Demons surged into a ripper and the big plasma primaris squad with attached liuetenant.
Then first turn went to Nids
