If i don,t pre-order the game will I be able to get the kill hitler DLC at a later time? As a separate purchase?

Usually when they do a pre-order it's a limited time type of thing, then later on it becomes purchasable. Doesn't always work like this however. I'm trying to remember if the "Play as Joker" DLC for Arkham Asylum on the PS3 ever made it to Xbox 360 or not.

With the mission, plus the weapons you get to access (SVT-40 and K98) I'd hazard to guess it would be purchasable later on just based off of that, but might want to be more safe then sorry.

which leads to another question, does the peeps that pre-order get to have another map/weapons over peeps that DONT pre-order? on multiplayer..

Yeah, generally pre-order guns and such not available to the masses are just different in look and that's about it. They usually come down to status symbol more then anything.

for example

"OMG he's got the Snipar K98, How do I ownz one?"

"Lol, pre-order the game n00b"

And then the ever popular entitlement phase of the scenario

"Hey guys, we'll be releasing the pre-order bonus's in later DLC"

"Nooooo the noobs be takin my Snipar rifles, we went through the trouble of pre-ordering, why shuld they be able to spend money and get it?"

lol

It will be sold separately at a later date.

I really want to know about this as well. It may sound silly, but if it is not offered at a later date then I wont get the game unless it is really cheap. Exclusives are stupid and quite annoying. Pre-ordering gives you the dlc on day one and it is 5 bucks cheaper than non pre-orders. I do not have the money right now, so pre-ordering was not an option. If game companies have no courtesy then screw them with there exclusives. Hopefully Rebellion will be different than other companies or they wont get my money. :)
