In one word: luitenant.The luitenant is a unique specialist that allows players to trade dice. This way you talk to other players (save me the red skull, nooo you rolled the blue soldier, etc...) so as to get many RWB.
In fact, I feel that the game becomes too easy with 2 or more players. Only the damage scales, but being able to trade resources and dice makes it much easier
