Resident Evil Gaiden follows the story of Leon S. Kennedy , an S.T.A.R.S. member who is sent to destroy a new Bio Organic Weapon on a cruise ship called the Starlight. The team has lost contact with Leon since he arrived at the ship, and it's up to you to find out what happened to him. As you navigate through the ship, you'll encounter undead enemies similar to those in the original Resident Evil series.
The gameplay of Resident Evil Gaiden is a mix of top-down side-scrolling action and 1st person shooter elements. You'll need to use a range of weapons and items found on the ship to overcome obstacles and defeat enemies. The game's objective is to get aboard the liner, destroy the weapon, and find out what happened to Leon.
