Abstract: The recent advancements in Brain-Computer Interfaces (BCIs) technology made possible for its employment in entertainment applications, such as brain-controlled games. However, there are still many challenges to overcome in the design and development of such applications, especially when considering the interaction between multiple users. This paper presents the results of a controlled experiment aimed at comparing the performance and game experience of both competitive and collaborative matches in a multiplayer BCI game. In the experiment, sixteen subjects were divided in pairs into two groups, and each pair played a total of five competitive or collaborative matches of the attention-based game. Quantitative and qualitative data were collected to investigate key features of the subjects' interaction with both the BCI platform and the other players. It was found that there is no statistically significant difference in performance between the subjects of both groups, and between multiplayer and single player modes. Although the group playing competitively reported overall better scores for game experience, there was no statistically significant difference between groups. There were significant correlations between performance and positive aspects of game experience for both modes, and multiplayer matches were significantly shorter than single player ones, although this effect could not be attributed to the mode of interaction alone.
