Safetys-Off says: "Without a doubt, the genre bending trend of including RPG elements in shooters is growing increasingly popular, with games such as Call of Duty 4 and Gears of War 2 featuring aspects of "XP" gains based on in-game accomplishments such as killing enemies or completing objectives. Typically, experience is awarded in RPGs for winning battles or defeating bosses, and it is this aspect of the typically slower-paced genre that is arguably the most addicting. Certain developers are taking notice of this kind of gameplay and infusing the concept with games that are of a completely genre. How can developers further stretch the boundaries of typical RPG elements finding their way into shooters?"
