Space Hulk Deathwing Arsenal Trailer

Space Hulk: Deathwing has released a new Arsenal trailer for all of you to enjoy! It features a huge variety of weapons, including the storm bolter, redemption storm bolter variant, force sword, assault cannon, thunder hammer and storm shield, plasma cannon and heavy flamer. I didn't see any multi-melta, so I don't know if that will be in the game.

Also shows the Mace at the end, but I think it will function similarly to the thunder hammer. We shall see. I prefer the heavy flamer, though.

What are your favorite weapons?
