The trick with The Western Front Armies is that players of TWFA can play against each other OR against players of the base Company of Heroes 2 game.
War Bulletins are out. Gone, forgotten, and now replaced with War Spoils. They function is a rather similar way, but do seem to have an element of randomness to them (or at least The Average Gamer could decipher no clear pattern after 15 odd hours of play). You still choose three of them per loadout, however, so don’t panic too much over the change.
