She quickly discovers that Alien Syndrome is behind the disappearance and decides to fight the enemy and find out what happened to her boyfriend Tom.

Players are accompanied by a robotic drone (SCARAB) that serves as a storage space for items as well as a backup for the main character.

As a constant companion, SCARAB can assist in fights and grant on-demand access to the character's cache of weapons and armors.

In addition, motion control-based minigames are available to the player to increase stats via DNA augmentation chambers found in various levels, defeat lock protection on golden chests with guided nanites to procure items with a variety of attributes as well as loot, and disinfect rare items afflicted by the Alien Syndrome with charged nanites to restore their attributes.

Both IGN[16] and GameSpot[17] praised the intuitive aiming controls, but complained about the lack of enemy variety and graphical difference between the Wii and PSP versions.
