Bionic Commando is a 2009 action-adventure video game part of the Bionic Commando series. The game was developed by Swedish developer Grin and published by Capcom. The game is a sequel to the 1988 NES game Bionic Commando with certain storyline elements taken from its 2008 remake Bionic Commando Rearmed. The game runs on Grin's Diesel engine. Bionic Commando is an action-adventure game in which the player controls player character Nathan Spencer. The game uses several mechanics (primarily radiation) which act as barriers. These barriers are used to keep the players within the confines of the linear level design. Nathan Spencer is able to target enemies while hanging climbing a building or even in mid-swing while using an implement called the 'Bionic Arm' which can also be used to attack enemies at close range. The bionic arm can be used to grab and launch objects such as boulders and cars at enemies. In addition he is equipped with boots that enable him to survive extremely long falls. Spencer is equipped with Tungsten gun which is shot quickly but does minimum damage to the enemies and Prototype gun which fires fast and does maximum damage and he can use throwables such as grenades. The weapon reload mechanism is missing in the game and players must try to find the ammunition to use them. Players can also use special weapons such as sniper rifle machine gun shotgun grenade launcher and missile launcher with limited amount of ammo. The ammunition can be found from the dead bodies and other parts of the game as well with exception of the special weapon ammunitions which can be found rarely. The ammunition can be categorised by its color i.e. orange ammo for primary weapon blue ammo for grenades and red ammo for special weapons. Spencer can also attack from a greater height by stomping the ground with his Bionic Arm causing to kill multiple enemies at once plus he can also hack drones and other systems with the attached arm. However due to the heavy weight of the Bionic Arm Spencer can not swim (although he could swim before he lost his arm) and as a result the players must find a way to get him grappled to a safe zone before he drowns.
