Halo 3 developer Bungie has come out fighting amid some complaints that the blockbuster FPS, available in the UK now, is simply "Halo 2 in HD".

Speaking in an interview with Pro-G at the launch of the game in London's Waterloo IMAX cinema last night, Lee Wilson, cinematic designer at Bungie Studios said the team was delighted with the graphics in Halo 3.

He said: "It's completely immersive. The art direction is immaculate. It's not trying to be incredibly photo realistic or painting this grimy world. It's vibrant and it's fun and it's accessible."

Despite wholly positive reviews of the game across a number of publications (you can see why Pro-G gave Halo 3 10-out-of-10 here) reviewers, including us, have pointed out that some areas of the game have average graphics, particularly the water effects and character models.

However, Joe Tung, multiplayer producer at Bungie Studios, was bullish in his response to those criticisms.

He told Pro-G: "Stuff like the water, stuff like our HDR (high dynamic range or next-gen lighting) model, I think that stuff is so beautiful and so subtle and over time I hope people will appreciate that stuff as much as we do right now.

"Something like the HDR is really beautiful but it creeps up on you over time while you're playing the game, the way the light behaves. Like I said we're really happy."

He added: "We think it's a beautiful game at Bungie. Folks who have complained about the graphics in the large part have said 'I don't like the way it looks' then they pick it up and they play it for half-an-hour and then four hours later they're still playing and that's the last time you hear them saying anything about the game."
