Before 27 May2010, it was called "Castlewars" and was unlocked while playing Castle Wars on surface. The instruments also have slightly changed, making it sound quieter and smoother, which was also done with Attack1. On that day, another track was released; Castle Warz, which you unlock when fighting for Zamorak. Both track were once again remastered on 9 April2013.
This track and its sister track, Castle Warz, end in the same letter as the first letter of the god's name whose team it plays on.
