Lethal Alliance focuses on shooting rather than lightsabers and the Force. The DS version of the game makes heavy use of the touch screen for gameplay, while the PSP version utilizes the handheld's buttons. The PSP version lets the player utilize "stealth" features such as stealth attack moves, sneaking past enemies, wearing disguises, while the DS version has an exclusive weapon called the Dual Cannon. The Dual Cannon can only be used once the player has obtained "Maximum Alliance" between Rianna and Zeeo. Once the Dual Cannon is used, it greatly drops the character's alliance bar, and must be filled to use again.
