The VR universe was originally conceived as a training device to prepare mankind for an alien invasion, but was hurriedly shut down when the system became self-aware and created a brutal world populated with virtual, yet hostile alien races. Cast as a hacker, the player is equipped with an array of hi-tech weaponry and must cleanse the VR world of its unsavoury denizens.

The game's virtual landscape is split into three distinct worlds and enjoys a lavish level of detail and lighting effects that show off the power of the Sony system perfectly, while eerie lighting and shadow effects add to the ever-present oppressive atmosphere. Similarly, Coded Arms' computer-devised aliens are equally impressive and range from enhanced soldiers, insect-themed species and robotic adversaries, each of which have certain vulnerabilities to specific weapons that the player can use to their advantage.

Coded Arms also ensures the player is suitably equipped for the tough task that awaits them. Over 30 different weapon systems are available, with machine guns and pulse weapons and sniper rifles allowing for blanket or precision shooting, while a variety of grenade styles also feature in the game's impressive arsenal. The game also makes use of the PSP's wireless capabilities, with up to four players invited to compete in the game's many multi-player modes. Any weapons collected by the player in the single-player mode can also be accessed during the multi-player games, further extending the longevity of this already engrossing shooter.

Coded Arms will be released for the PSPTM handheld video game system in Q3, 2005.
