You always could pre-order the game and if the modes aren't included or if you just don't like the feel of the game, you could always use the refund option. Hopefully you won't need to use that but it is a option.

@ldclaudius sounds like you're talking about Outpost and Operation. To the best of my knowledge, Outpost isn't one life and Operation, assuming it follows suit with every other co-op mode, most likely won't be one life either.
