The conflict level (Level 10) for the aliens in Mars mission is Nightfall. (If you want the special ops codes for the aliens then I'm sorry but I think no one knows, wait about a week though and some Nerd will come across the cheat after typing away at his computer for hours straight.)

Well you try being a game designer its a hard job you know!!! Its because they could make another ben 10 game following it with different aliens on so they can make money or it could be because they cant use all the aliens abilities in the game or if it's hard to think up all the combos for all the aliens.
