Sodium One, also known as Sodium One: Salt Shooter, was a tank shooting game released in 2009 for PlayStation Home. Originally only available as a private space (Single player), a multiplayer version was released on 6 October 2011. The first five levels were free to play. Beyond that, the player had to purchase the game.
Gameplay[]
The player controlled a hovering battle craft. The left analog stick controlled the direction the craft moved, while the right analog stick rotated a turret on top of the craft. It was very similar to many other popular tank games with the exception that these tanks hovered.
The primary objective was to aim at, shoot, and destroy waves of oncoming enemy craft. Most levels included multiple waves of oncoming enemies. Some were simple craft (Similar to the player's craft) while others were stationary towers that caused extensive damage if the player got too close.
A secondary objective was to collect raw materials. The raw materials could be sold in the Hub for Sodium Credits which the player could use to upgrade weapons and armor, improving the chances of success in higher levels.
Sodium Hub[]
The Sodium Hub was the landing space for Sodium One and later its sequel Sodium 2: Project Velocity. It featured an A.I. named VICKIE who issued objectives and allowed players to spend their earned Sodium Credits on various rewards. The space was also home to multiple mini-games, each rewarding the player with credits:
Scorpio's[]
A bar in the hub named Scorpio's featured a mini-game where players could choose be a customer or an employee.
As a customer, the player would order a drink. An employee would then fulfil the drink order and the customer would drink by pressing the button shown sliding side to side on the screen. As the button reached a side, the symbol could change between 
, 
, or 
. The player then needed to press the corresponding button on the controller when the sliding button reached the middle of the display.
As an employee, the player would take an order from a customer. The order had four parts: a cup, a drink color, a primary decoration and a secondary decoration. The employee would then fulfil the order and deliver it to the customer.
Scorpion Stomp[]
There were two scorpion breeding grounds in the hub where the Scorpion Stomp mini-game could be played. The goal was to stomp on and kill scorpions. To do so, the player would approach the scorpions from behind and run over them. Success in stomping scorpions without being stung increased greatly if the player wore the special scorpion stomping boots available to purchase from the Sodium store. There were vending machines that provided drinks that made the player immune to scorpion poison for a short time.
Tank Trainer[]
Tank Trainer was a mini-game that acted as a practice of the main gameplay in a small enclosed training field. Robot crafts would come out of two launching locations and the player would attempt to shoot them. The controls were identical to the main game.
