Firstly, the date has been moved to April 18th, a month ahead of the expected date. It also reaches the system with a bunch of new features, all detailed below.

Upgraded graphics The graphics have been optimised for the GameCube, taking full advantage of the chipset. Explosions are bigger and better, the screen shakes for nearby explosions and impacts, there's more tracer fire and it looks better than ever.

The AI and other functions have been retuned to turn out a higher frame rate, and optimised for other gains, like faster reloading times

How's your aim? This version also has new "Dynamic Aiming" sights. This new crosshair system shows accuracy levels depending on the character's stance and movement, but without obstructing gameplay. There's also an upgraded auto-aim, which with a tap on the fire button raises the gun and tracks the nearest target.

There's a new smooth-scrolling inventory for more efficient management of equipment, and a new shortcut system that allows the player to jump directly to key items - like medikits - packing in all the functionality into the GameCube's joypad.

And it keeps getting better... Even the best can be improved upon. Feedback from the other format releases asked for a 'Restart Level' feature, which allows the player to restart from the in-game menu.

Enemy AI has also stepped up a gear; soldiers will hunt around for players using sound to track them, they back away from suppressing fire, and they'll remember where they last saw you.

Four pads are better than two The icing on the cake for the GameCube is the split screen multiplayer for 2-4 players, which lets you tackle each mission with your mates in co-op mode.
