Can you play as alien x in ben 10 alien force video game
No sorry you can't, not in any of the systems.
You can play as Swampfire,Humongasaur,Big Chill,Jetray,Spidermonkey in all systems,
and extra aliens available on the DS are Chromostone,Goop,Echo Echo.
So you don't get to play as Alien X or Brainstorm at all.
