Spitter

The Spitter is a quadrupedal horned creature that is aggressive to players and will spit fire projectiles at them. It has 40 health and will drop Alien Organs when killed.

Behavior
Aggressive Creature. Attacks the player on sight with a small exploding fireball projectile that deals 10 damage. If engineer gets too close to the spitter, it will attack him with a short ranged fire explosion dealing 5 damage and knocking the engineer back.

Alternates between the following behaviors: Strafing, Approaching, Shooting.
 * During Strafing, the Fire spitter circles the Player.
 * During Shooting, the Fire spitter stops moving for a short time, faces the player and attacks. Its mouth will glow yellow before shooting a fireball.
 * During Approaching, the spitter follows the player / tries to get closer. With this behavior, it can attack while moving.

Strategy

 * Since it always directly faces the player when shooting, close combat is difficult. If a Rebar Gun is available, wait till it targets, shoot and immediately jump and move to dodge the slow flying fireball.
 * Approach it with a Xeno-Basher, try to handle one at a time. Its mouth will start to glow yellow, ready to shoot a fireball. Move sideways and misdirect its fireball. After it shot the fireball, change your direction of movement and dodge it. Charge to the spitter and double bash with your Xeno-Basher, but don't attack the third time. Back off, it will shoot another fireball and will probably miss you, as the fireball will hit the floor instead. Approach it and bash for another 2 times and it should be dead.
 * You can negate a spitter's fireball attack by hitting it with a Xeno-Basher.
 * Spitters will try to anticipate the player's movement and will shoot in advance. Use this property to your advantage.
