Arcade

Differences Between Killer Queen Arcade and Killer Queen Black
The core goals and concepts are the same or similar, but the gameplay styles are different - for example, in KQA (the arcade version), there is no attack button, and kills are determined by Height a-la Joust.

Arcade is 5v5 whereas the black version is 4v4.
