UNITS are beings that you control and play with in the game. Units are clones of each other and are generated, hired or bought in potentially infinite numbers.

Common characteristics:

  • Die permanently
  • Are purchased/hired in large quantities
  • Can be upgraded
  • Have attributes and/or abilities


  • Troops that you train from barracks or other buildings (e.g. Barbarians in Clash of Clans)
  • Towers in tower defense games, if there are no limitations to the amount of towers to be built per stage (e.g. plants in Plants vs. Zombies 2)


A single entity in a game can be classified as only one of the following: CHARACTERS, UNITS, or BUILDINGS! For example, UNITS are not CHARACTERS, as UNITS can die permanently and can be trained/created from e.g. barracks in large numbers over and over again if you just have enough resources.
