This post includes a series of videos which I am using for inspiration.
Call of Duty 4: Modern Warfare
In Call of Duty 4, the opening mission serves as a tutorial to teach the controls and mechanics to the player.
The player learns how to perform movement, jump, aim and shoot, use weapons, and go prone.
Counter-Strike: Global Offensive
In Counter-Strike: GO, the game has a training mode which allows the player to learn the basic mechanics.
Overwatch
In Overwatch, the game includes a training mode.
Conclusion:
In this training mode style arenas taken from commercial videogames, I have concluded that lots of these areas help teach the player the basic mechanics and controls of the game. I would be interested in going for a similar design in my game. These games include teaching mechanics such as shooting, jumping, running, crouching and using in-game items. These mechanics are ideas which I will keep in mind when creating my game.
