Coded Arms Contagion is the sequel to Coded Arms. The gameplay is similar to the first game, Coded Arms. However, this time player has only 13 levels (and a training) with no random geometry, plus challenges which are available upon completion of a level. Full Motion Videos, storyline and much bigger landscapes are present. The player has to collect special point to upgrade his armor, health, and weapons. A new feature is included: the ability to hack computer panels, doors and turrets. The game's levels are divided into three portions: Industrial Zone, Military Zone, and A.I.D.A. Core. The only step back (compared to the previous title) is the absence of ragdoll physics.
