Editing Action game (section)

=== Obstacles and enemies ===
In action games that involve navigating a space, players will encounter obstacles, traps, and enemies. Enemies typically follow fixed patterns and attack the player, although newer action games may make use of more complex [[artificial intelligence]] to pursue the player. Enemies sometimes appear in groups or waves, with enemies increasing in strength and number until the end of the level. Enemies may also appear out of thin air. This can involve an invisible spawn point, or a visible generator which can be destroyed by the player. These points may generate enemies indefinitely, or only up to a certain number.<ref name="fundamentals"/>

At the end of a level or group of themed levels, players often encounter a [[boss (video games)|boss]]. This boss enemy will often resemble a larger or more difficult version of a regular enemy. A boss may require a special weapon or attack method, such as striking when the boss opens their mouth, or attacking particular part of the boss.<ref name="fundamentals"/>
