The player collects power-ups in the game that increases an individual character's abilities. Gun icons increases firepower, K-rations recovers energy, and Chevron icons increases the current character's maximum stamina. Bullet icons refills the player's collective ammunition and bulletproof vest icons that grant temporary invincibility are also available at designated locations on each area. Icons flashing in red are more valuable than ordinary icons. All upgrades garnered during the course of the game are permanent, provided of course the character survives the mission.
