All of the levels in the game are randomly generated when they are accessed. In single player mode, players progress through the game by completing sectors. Sector 00 consists of one battlefield (Training) with 3 levels that serve to familiarize the user with the game. Sector 01 consists of three battlefields (City, Base and Ruins) and each battlefield has 6 levels. Sector 02 also has three battlefields consisting of 13 levels each with a boss at the 13th level of each battlefield. Sector 03 consists of one battlefield (Infinity) which has an unlimited amount of levels to it. The difficulty of the game increases as the user progresses through the sectors. Players can also make use of a 3D map graphically similar to a vector display. Coded Arms also has wifi support for 4-player multiplayer with three game modes including 'Deathmatch', 'Keep the Mark' and 'Last Man Standing'. Weapons and armor are obtained throughout the levels and have one of five different attributes, ranging from "physical" to "fire" as well as specific attributes such as "electric" or "viral". Certain attributes are more effective against certain enemies - for instance, mechanical enemies can be overloaded by weapons with the "electrical" attribute while insect-type enemies usually dwell in the dark so "light"-type weapons do the most damage to them. Enemies also use weapons with different attributes and therefore one can get certain types of armor that are resistant to attacks of a certain type. All of the weapons and grenades can be upgraded by picking up a certain amount of "Opt_Key" files (the amount varies from weapon to weapon). Because the game takes place in a computer program, the equipment and pickups are named with extensions much like in a conventional computer (for example ".arm" for weapons & armaments, ".dfn" for armor and defense items, ".med" for health pickups etc.).
