Through more playtests and design discussion, the framework was laid down for Left 4 Dead core concept of a "Co-op vs. According to L4D team member Mike Booth, while experimenting with the AI for non-player bots the dev team found that the concept of "Small team of friends against hordes of clawing enemies" had a great deal of potential. Left 4 DeadĮarly design of Left 4 Dead came about in 2004 after the release of Valve's classic tactical shooter Counter-Strike: Source. Hordes of "Infected" bar their path at every turn throughout the four campaigns, and working together as a team is often the only way players are able to achieve success, especially as many of the challenges posed by game mechanics and obstacles players face require more than one individual to complete. An action/survival first person shooter, L4D puts the players in control of four survivors battling their way to safety during a zombie apocalypse. Through reviewing how players move from a knowledge based behavior to rule based or skill based behaviors (or vice versa), designers can assess the effectiveness of a game mechanic and make adjustments as necessary, such as simplifying or adding complexity to the mechanic itself.Īn example of a game that was developed with clear emphasis on what and how players think can be found in Valve's Left 4 Dead, released in 2008, and its sequel Left 4 Dead 2, released a year later in 2009. Therefore, game designers can use this tool to identify how players engage a game mechanic during gameplay.

Therefore, in the context of electronic gaming, players of a particular video game will engage its mechanics using cognitive behaviors that can be assessed and classified by designers using the SRK Framework. A longtime gamer who's never played any form of major MMORPG, for example, would very likely engage in knowledge-based behavior in order to understand the functions of a typical interface from that particular game genre.Ī strength of the SRK framework is that it is broadly applicable to virtually all interactive activities.

An example of a skill based behavior common to console gamers is using the left and right thumbsticks to look around and move an avatar in game.

If a mechanic is too complex for players to understand, the result may be player frustration, whereas if a mechanic is too simple, it can quickly lead to player boredom and repetitive gameplay. Yet in their design a crucial factor can be overlooked with regards to how game mechanics are made or adjusted through the development process: understanding the ways in which players think and learn about the function of game mechanics is key to determining their effectiveness. They are the primary method by which players are able to operate in a game environment to overcome the challenges and obstacles that a game's developers have placed down. Mechanics are the core building blocks of any game.
