Coded Arms: Contagion is a direct sequel to the Coded Arms game, and the second game in the series. The player takes on the role of special agent Jacob Grant and enters a virtual reality combat simulation program called A.I.D.A to stabilise it and enable its proper use.
The player's goal is to contain a digital virus that has spread through earth's networks and ran loose, allowing humans to digitize their personality for a chance to hack inside the system. However, after the virus is contained again, Jacob discovers that the program is still not stable.

The player can also hack into turrets by solving numbers and turning them against their masters. There are thirteen missions in total, including multiplayer options on five different maps for up to eight players.
