The Force Unleashed is a third-person action game in which the player's character's weapons are the Force and a lightsaber.[7] Developers treated the main character's lightsaber like another Force power, and wanted to ensure "something visceral and cool" happened with each button-push.[7] The game has a combo system for stringing lightsaber attacks and for combining lightsaber attacks with Force powers.[7] Experience points earned by killing enemies and finding artifacts can be used to increase Starkiller's powers and traits.[8] The gameplay is intended to be easy to learn; the development team included "horrible" gamers to help ensure the game's accessibility.[9] Players can casually run and gun through the game, but the game rewards those who take a stealthy, more tactical approach.[9] The game includes enemies that are easy to overcome; game difficulty arises from presenting these enemies in large numbers that can wear down the player's character.[10] Additionally, enemies learn from the player's character's attacks; using the same attack on different characters can sometimes lead to the player's character doing less damage.[11] The enemies, which number over 50, have various strengths and weaknesses; developers faced the difficulty of effectively placing them throughout the game's varied environments.[10]
