Ben 10 converts into an alien to fight the hypnotized guards and to find out what exactly is going on. The only alien Ben 10 can convert into in the beginning of the level is Benwolf.

When you have enough energy you can perform a special attack pressing Space. When you discover other alien forms, you can select other aliens holding C and pressing the arrow keys.
