At the top center corner is the timer.
On either side are Omintrix and Antitrix symbols. These act as your combo meter.
Begin by choosing an alien.
You start with two aliens (Heatblast and Shock Rock)
Unlock three more by beating Arcade mode:
Attack as many times as you can until they run out of hit points.
Use the right arrow key to attack.
Each attack you land helps build up your combo attack.
Defend yourself to prevent your enemy from striking a hit.
Defend by selecting the left arrow key.

Once you’ve earned enough attacks, begin the combo by pressing the space bar.
Press the right arrow key as much as you can to fire up the combo.

Fight against five of Kevin’s Antitrix aliens.
After each battle, you unlock another alien in Ben’s Omnitrix.
Fight against an endless barrage of aliens.
As with Arcade mode, you have two rounds to go against the aliens.
Keep fighting until lose to one of the aliens.
Beat your best score by fighting more aliens than you did before.
As with survival mode, fight as many aliens as you can before one of them beats you.
When each fight begins, you and your opponent receive a different “bonus,” though how helpful that bonus varies.
Some, such as extra hitpoints and added speed, are beneficial.
Others, such as reduced speed or poisoning, hinder your ability to fight and outlast your opponent.
The bonuses are assigned at random. You’ll never know what you’ll get until the start of the round.
This game is suited for older children and fans of the Ben 10 reboot series.
The game has no adult content.
