With every iteration, I conducted playtests of a full match of 6 player FFA DeathMatch, observing player behaviour, asking questions, and afterwards going over survey data. All of this data is documented in this playtesting log.
These results formed the foundation for every iteration of the level; going over the data, interpreting and relfecting on it, forming action points, and then going back in editor to make adjustments.
Together with the iteration log, these documents provide a comprehensive overview of the playtesting/iteration process.
