When do you get all 10 aliens in Ben 10 psp video game?

Answer 1

It depends what console your playing it on.It only works on DS and it works like this. I dont have a DS myself but the code for upchuck is A, Left, Y, Right, X, Up, B, Down, Select. I AM 90% SURE THIS WORKS!!!

Answer 2

Answer: You'll unlock the eleventh, Cannonbolt, at your tenth victory in Battle Mode. You'll unlock the twelfth, Wildvine, at twenty-five wins. Gain #13, Upchuck, at thirty-five wins. The fourteenth and final alien to unlock is Benwolf, gained at fifty wins. You need to keep a winning streak, and it cannot be broken by a loss. You can take a break from the game and it will still keep your streak.

Answer 3

it takes if you want all aliens in psp you download it from your computer just type the cheat you want
