In Ice Nine, players take control of a CIA agent who's failed his training at the hidden Camp Peary in Virginia, only to be recruited for a secret mission. Based on the feature film The Recruit starring Al Pacino and Colin Farrell, gameplay features the first-person engine used in Duke Nukem Advance. Players will shoot enemies, plant bugs, knock people unconscious, and undertake sniping missions. Enemies are smart, reacting to gunshots, and the environment is surprisingly interactive with animated surfaces, fragile objects, and vertical scrolling. Multiplayer options include four-player deathmatches when using the supported Game Boy Advance Link Cable.
