Adding onto the review, I didn't play raid mode until this morning because when I wrote the review it was already 12 AM. Raid mode is basically what it sounds like. You go into an area with the goal of getting to a certain objective. Whether or not you want to kill all the enemies is actually up to you. However, there are some areas where you have to defeat all the enemies to advance. Raid mode also works on a "level" system. Essentially, whichever character you choose will gain experience as you progress through the levels and defeat enemies. There's also an out of level store, where you can purchase weapons and upgrade parts for them. You gain the points by playing the game.
