Pokemon Ranger Shadows of Alma

This is the first game in the Pokmon Ranger series to feature Pokmon
from Pokmon Diamond and Pokmon Pearl. Pokmon Ranger is a unique
action-adventure series that features a fun, different way to capture
Pokmon with the Nintendo DS stylus, which controls an item called the
Capture Styler in the game. Players circle the Pokmon they want to
catch by drawing circles around them on the touch screen. When you
complete certain Quests, the Ranger Union awards you with power-ups,
which add new upgrades and functions to your Capture Styler, allowing
you to advance as you work to eventually become a Top Ranger.
