Nintendo DS version From a first-person perspective, players must navigate through dungeons and environments in a 3-D world, battling enemies while searching for items, secret side areas and ways to unlock locked doors, whether with keys or
magical spells. Both
swordplay and sorcery are at the player's disposal, controlled using the Nintendo DS'
stylus and
touch screen, and the more frequently a player uses either means of attack, the stronger it will become. Players can also use
shields to block and reduce damage from enemy attacks, or evade them with quick steps via
circle strafing and an automatic lock-on system. To cast magic spells, whose names are
ancient Greek words (for instance,
astrape for thunder and
iaomai for healing), the player must trace out
runic Kirie symbols across a 3 x 3 grid, using one unbroken stroke of the stylus over select squares in the grid. Spells cost
mana and most spells must be learned either through
leveling up or from reading Kirie slates that will teach particular spells. Players can only
save their progress by talking to certain
non-playable characters, and save points serve as
checkpoints; should the player fall in battle from losing all
health or getting hit by a death spell, unsaved progress is forfeited and the player must reload a previously saved game. Shawn and Ace's story also makes use of the microphone, in which the player must blow or scream to it in order to advance the story. ==Development==
