It's solid gameplay, immense replayability, online functionality and incredible production values will ensure its place in video game history, and it is, without a doubt, a satisfying and fulfilling close to the beloved trilogy[?].

The Forge is a gargantuan achievement that puts game design in the hands of players, daring you to be creative and invent a Halo 3 multiplayer experience all your own. Of course, the multiplayer is every bit as astonishing as it has been in past iterations and even eclipses its predecessors in many respects.

The best game yet in one of the best FPS franchises of the era. Better than either of its predecessors, Halo 3 still can't quite escape the category of flawed masterpiece - but this time around, the flaws are so minor that even the most churlish of reviewers would be hard pressed to mark the game down.

The single player is bigger and brawnier than anything that's been attempted on a console before. The multiplayer, which already shadowed the competition, has improved to the point of ridiculousness. The new features - Forge, Saved Films, Coop - are frighteningly addictive. And if you don't like any of that, you're always welcome to edit it until you do.

It's hard to imagine a feature of this game that someone won't love... Sure, no one aspect of the game is life-changing on its own, but perhaps the package as a whole is. After all, Halo 3 has enough content to keep you stuck to your controller for weeks, if not months or even years.

Halo 3 transcends video games. It is a global entertainment experience. Just as "Lord of the Rings: Return of the King" and "Spiderman 3" brought to a close two of the most lucrative and epic film trilogies of all time, Halo 3 brings to a close perhaps the most complete, engaging and downright fun video game trilogy of all time. There is absolutely no way any Halo fan will be disappointed by this game.

Halo 3 is the gaming equivalent of a Hollywood blockbuster. It's not going to revolutionise the genre - it's not meant to - it's meant to be great fun, which it is. Never lose sight of that. The visuals, guns, vehicles, enemies, set-pieces, musical score... they've all been cranked up to 11 to create an experience up there with the best sci-fi properties.

Halo 3 is the best Xbox 360 game to date. The single-player campaign and storyline are both very strong, but it’s Forge and the Saved Films features that will likely go down in history as Bungie’s crowning achievements. They’ve basically taken everything great about the series and improved upon it in every way, then added some amazing new features that we’ll be using for years to come.

Worth Playing
Between the ability to come up with your own bizarre custom modes and the theater mode, which records damn near everything you do with crystal clarity and allows you to play it back from multiple points of view, the worst thing you can say about Halo 3 multiplayer is that it’s going to force you to buy an Elite 360 just for the sake of having more hard drive space.

The campaign, which is very good, is Halo 3's weakest point. It doesn't capture the cavalier spirit of the original Halo, but you'll still have fun playing through it. There's no first-person shooter on 360 that can equal Halo 3's blend of cinematic action, adrenaline-pumping shootouts, and male- (and female)-bonding gameplay. Look beyond the gameplay and you have a rich feature set unlike anything ever delivered in a videogame.

Halo 3 takes every positive aspect from the first two Halo games, perfects them, puts them in a shinier and better looking package, tosses in wonderful community-driven content for a console game, establishes some awesome environments, and does it so damn well it's impossible to not have fun while playing.

It's the addition of the Forge level editor and the saved films that give the game an even longer set of legs, legs that will probably keep you running at full speed until Bungie figures out where, exactly, to go from here.
