Call of Duty: World at War has a lot to live up to. The venerable Call of Duty franchise was taken to new heights by Infinity Ward's Call of Duty 4, with DS specialist n-Space doing a cracking job of the DS version, so expectations are high. So, what does World at War, developed by returning developer n-Space, have to offer? Well, the series has also gone back to the war that made the Call of Duty series famous - WWII. Rather than tread the same old battlefields, however, players will be thrust into the muddied boots of Russian and American soldiers on multiple fronts. A heavy emphasis has been put on the Pacific Theatre, meaning players will have to take on Japanese soldiers deploying kamikaze attacks, ambush tactics and Banzai charges. This also means a different slant on gameplay. You won't be charging into rooms to blast all and sundry so much as you'll be crawling through jungle undergrowth to make your kill. As with CoD4, play is rounded out by seven mini-events, with challenges such as mine defusion, mortar strikes on enemy bunkers and manning an anti-aircraft gun to take out enemy planes. Online play makes a return, offering those wanting to make use of the DS's Wi-Fi connection the chance to take part in four way multi-player battles. For the more dedicated player, there's also the opportunity to track your stats online. The world needs you for fighting duties again. Time to step up.
