It's up to you and your allies to roam around the map looking for supplies and carry them to the truck. You'll have to beat the enemies, who'll try to get their hands on the supplies as well. Those who manage to carry the most supplies to the truck will win.
Your job is to capture the supplies and not let your opponents gain control of them! The team that captures the supplies starts earning points. The team who has obtained the most points at the end of the match wins.
