There are different requirements for each to spawn: 1 might require u to get a certain combo another might require u to kill an enemy in a specific way, like with a trap. I just found about this feature today and the game doesnt stop surprising me even now, thats something.
Nope i doubt any1 knows for sure this early, right now they r still guesses but in a week might start checking, maybe some1 will have written a faq by then.yes i understand this and that is what i was wandering if any one knew "what are the requirements for each stage?"
just throwing this in here, concerning Mercenaries. so is Mercenaries possible to play, to not being connected (online). cause i am a xbox 360 user and currently hold a Gold Live subscription for 3 months and it will expire on December 24? i think, recalling a notice from Microsoft (Xbox 360). cause i have unlocked Helena, thanks to Ne0 (and will be definately be as her *Helena* when doing Mercenaries). and would like to most definatly enjoy Mercenaries when i finished all the campain.
yes you can still play mercenaries off line solo and split screen, but the agent hunt you will not be able to play because it is strictly online game play
