There is also a returning alien, Cannonbolt. Unlike Ben 10: Protector of Earth and Ben 10: Alien Force, the game doesn't features a co-op mode.
Now the Omnitrix doesn't time out also being defeated as an Alien will not revert back you to Ben, instead being defeated as an alien will make you lose.
And there is a reason for aliens being locked this time. Unlike Ben 10: Protector of Earth and Ben 10: Alien Force, the gameplay is diffrent this time.
