Projectile

During the early Doom years (1993-1994) the word 'projectile' was only used to refer to the damage-inducing things that players or monsters fire/throw using their ranged attack(s). Since then the term has broadened and currently any thing with certain missile/fireball-type characteristics and/or behaviour is usually categorized as a projectile. This includes Lost Souls, who are treated as such by the algorithm.
