Achievements are extra challenges which sometimes carry a point value or unlock bonus material, and are sometimes solely for bragging rights. Those are available when the player completes a certain task and range from simple tasks the player would do anyway, such as completing a level or defeating a boss, to more complicated challenges, such as killing a certain number of enemies in a specific way or completing a level without firing a gun.
