Entities 3 Versions of themselves, change depend on environment objects (Original, Overpowered, Underpowered)

• Heal Area (Increases health when stood on)
• Damage Area (Decreases health when stood on)
• Rage Area (Increase attack damage, bullet amount; decrease shot delay, hurt damage; player score points from killed enemies is boosted; the effect lasts for 8 secounds, requires recharge for 60 seconds)
• Equipment booster (Decrease shot delay, spread; increase bullet speed, bullet amount)
• Equipment dampener (Increase shot delay, spread; Decrease bullet speed, bullet amount)

GENERAL ENEMY Behaviour:

• There is a slight chance that an enemy will cause an explosion caused by a weapon:
  • Any gun
  • Axe
• Enemies caught in explosion will receive damage and have a higher chance to explode too
• Players caught in explosion will also receive damage

Gunner Behaviour:

• If the player has a gun, increase the engage range radius,
• The closer the player is, the lower the spread angle, increase amount, lower shot delay
• If the player is attacking (pressing attack button), lower the shot delay for 2 seconds

Ball Behaviour:

• If the player has a gun, reduce cooldown duration
• The closer the player is, the faster the ball will roll (add acceleration/decelleration)
