The game uses a first-person perspective. Players move through linear missions, fire weapons, use explosives, complete objectives, and sometimes operate vehicles or mounted weapons. The campaign progresses through scripted stages with changing locations and mission goals.

A DS-specific touch interface supports aiming and interaction, while the campaign supplies new weapons and situations as it advances. Multiplayer modes provide additional matches separate from the story campaign.

Conserve ammunition when possible and search each combat area before advancing. Use cover, prioritize enemies with heavy weapons, and follow the objective indicator rather than rushing through scripted encounters.

During vehicle and mounted-weapon sections, focus on the targets required by the current objective; destroying every enemy is not always necessary.
