We had a new game modes day at Plamojuku yesterday.
I had a couple of games of "Doorcry" (Warcry with the new Catacombs expansion), and I really liked it. It is similar to Kill Team Arena in the basic functionality of the rules, but it is *not* trying to be hardcore Matched Play and has a bunch of good old Warcry nonsense. Doors can be breached with a double or opened with a lever, and when opened don't close again. Bridges can collapse! I killed one of Kuroi-san's ridiculously OP Flesh Eater Courts things by running a little rat onto the bridge and sending both of them into the lava

Various bits of dungeon terrain have special rules, like breaching walls or being haunted, it's fun.
I ended up winning both games largely through good luck on the missions we rolled up (though to be fair, a pretty large proportion of the mission table feels "lucky" if you're Skaven). Kawamura-san used the new Scions and they looked awesome but as usual his luck betrayed him and he had super low ability rolls all game so didn't get to exercise any of their shinier new abilities.
We also played Arena Mortis, the multiplayer mode for Underworlds, and it is great. The constant respawning fighters, ridiculous upgrade stacks and the mechanic of stealing a glory from the leader if you kill them makes for a really dynamic game, and for us it stayed close until the end in both games. Ochiai-san won the first with some very cunning Ironjawz play, then I managed to tough out the second with an extremely katai Ironsoul.
Next time is the 14th, hoping to have the Scions painted up myself.
