Those casualty figures will make a nice addition to the 'flavor' of the game - just don't forget to use them in the 'heat' of the moment when running the game!
(I know about this from personal experience.)
Speaking of 'flavor', I hope when we see the game in 'full flower' that you've included lots of scatter terrain: carts, tables, boxes and barrels and such representative of the movie. Again, not strictly necessary, just elevates the game from a fine meal to a gourmet one - if only for the eyes.
Looking forward to the full reveal - even if we must wait until after the games are run to avoid giving away too much to potential players.
