Castlevania: Dawn of Sorrow (2005), the first installment of Castlevania on Nintendo DS, is a direct sequel to GBA hit Castlevania: Aria of Sorrow.
Like its predecessor, after finishing the game, you can choose to ignore pretty-boy Soma Cruz and instead play as Julius Belmont. Unfortunately, it seems that Julius's skills have waned a bit since his last appearance (http://tasvideos.org/2689M.html). Yoko Belnades and Alucard easily pick up the slack, though.
This run avoids the use of large-skip glitches that can be seen in our other run of Julius in Dawn of Sorrow (http://tasvideos.org/2459M.html), showing off more of the game.
