Army of One is an online first-person shooter in the post-apocalyptic genre. You have to fight with other players in various modes from 1v1 to 32v32 and show that you or your team are the best. In ranked mode, you can compete against people of your own level based on rank and skill level to have fun and prove that you are the best. There are also both individual and team weekly tournaments in demolition mode, where you need to blow up the enemy base.
