I rarely touched the other aliens, besides using them for puzzles.
I found Spidermonkey to be the most useful because of its speed and Humongousaur because of its strength. As appealing as the different forms are, it exposes perhaps the largest issue with the gameplay, which is that there isn't really a reason for using every single form. As a result, players will need to focus on combos and save their special attacks for finishing blows instead of constantly wielding them in battle. However, there is one gameplay element that players should be aware of: using a form's innate abilities drains energy from Ben's Omnitrix meter, preventing them from continually being used until the meter can recharge. Each form has different combinations and special attacks that it can execute, and Ben can unlock new abilities by defeating enemies and collecting glowing energy orbs. For example, Ben might need to change into his Humongousaur form to break through doors, or use his Swampfire form to ignite flammable substances. For the most part, gameplay across the seven included worlds is a balance of action and puzzle-solving that revolves around the skills of Ben's alien forms.
