Return Fire

In Return Fire, the player's goal is to capture the enemy flag and return with it to their base.
Return Fire has four specialized vehicles, each one with unique abilities for a different mission. Each vehicle can carry a limited amount of fuel and ammo (which can be refilled at ammo tents and fuel depots) and can withstand different amounts of damage. If a land vehicle runs out of fuel it stops and the driver jumps out and runs away. If a player's vehicle is destroyed, a skull wearing an army helmet materializes, taunting the player with laughter.
