Gear[edit]
The player can upgrade their armor to make it better and stronger but these cannot be purchased and are unlocked as the player progresses through campaign mode. The players start with Basic body armor, upgrade to Medium after completing the Afghanistan mission, and are granted Heavy body armor after the Aircraft Carrier mission. Players can also unlock and purchase new face masks that the main characters wear.
 
Customization
The game allows weapon customization, bought with money earned as the game progresses. Such elements as new barrels, stocks, forend-mounted vertical grips, and extra-large magazines and ammo drums that can be swapped out to give the weapon a unique look and superior statistics. Other modifications include suppressors, a gun-shield, an underslung grenade launcher, or an underslung 12-gauge shotgun.
A firing range feature was proposed that would allow the player to test out their newly customized weapon, however it was removed as it did not meet the developers' standards.
 
Vehicles
The original game boasted three different drivable vehicles: a jeep, a main battle tank, and a hovercraft. Gameplay was designed so that one player would drive and the other would fire a secondary weapon like a ring-mounted XM312 heavy machine gun (jeep and hovercraft) or a 120 mm cannon (the tank). The jeep and tank were removed from the final product due to "pacing issues" and the hovercraft was used only in the China and Miami levels.
