Ben finds out about Doctor Animo using the Alien DNA to create a mutant army. He gets another crystal and unlocks Wildvine. Ben tracks down and defeats the mother plant in Seattle. Kevin 11 is then drawn in the Null Void again. Kevin 11 kidnaps Max and escapes to the crater lake, where Ben defeats him. In San Francisco, Ben learns that Kevin escaped from the Null Void and brought some plant creatures along. By defeating Enoch's mech, Ben acquired another Omnitrix crystal, unlocking XLR8 and later, Cannonbolt. Enoch is building a mech using technology from Area 51 in an attempt to stop Vilgax and though he is also trying to save the world, he isn't willing to let the Tennysons help. Ben later finds Vilgax's drones and the Forever Knights fighting. Ben finds that the stolen DNA is being used to power various robots in the form of Omnitrix Crystals, and in destroying these robots he regains some of his alien forms. At the start of the game, a mosquito-like drone extracts much of the DNA from the Omnitrix, leaving only Fourarms and Heatblast on the watch. Overall the game is very good and recommend for hardcore Ben Alien fans for gamers seating for game this a rent due to being short. Alien foe plays like this game then viilgax attacks plays like cosmic destruction. Vilgax attacks and ultimate alien cosmic destruction. Just to remind you the aliens are heat blast,four arms,xlr8,canon bolt and wild vine. Controls are good and try support the same graphics for each system release. The gameplay is a side scrolling beat em up. If you finish a level very fast you unlock a video and artwork. The game is very easy but there are some challenges that are quiet hard. You're first aliens are four arms and heat blast you also xlr8 in the first mission boss.the forever knight boss gives you canon bolt while the plant boss gives you wildvine. As Ben looses his forms he now has to recover them by beating bosses. Pretty good but does it being easy and short gameplay affect the game.
