Resident Evil 4 marks a new chapter in the Resident Evil series. You`ll rejoin Leon S. Kennedy six years after his first mission as a rookie cop from Resident Evil 2. Now a US agent, Leon is on a top secret mission to investigate the disappearance of the president`s daughter. As Leon, you must make your way to a mysterious location in Europe, where new enemies await. Take them down by using enhanced aim-and-shoot features and a new action button.
The mobile (and Zeebo) edition of Resident Evil 4 follows the same plot of the original game, but the gameplay is divided in 12 separate chapters instead of the original continuous-flow gameplay, with cutscenes binding one chapter to another. Leon is controlled from the same over-the-shoulder viewpoint, but he can't walk and shoot at the same time.
The game also features a Mercenaries mode, with 24 timed stages, each with different goals such as surviving for a certain time or killing as many enemies as possible. The Merchant is also present and the player can use the currency earned in the game to buy new weapons and items.
