It may not be the best or the worst game but its definitely something. I enjoyed it very much as it came out when I was Ten. The game was not even close to being too violent for my age, and it was some good sequel to the DS adaptation for Call of Duty: World at War. I highly recommend this game if you've never played it for its pretty mediocre but fun story, about going around places and chasing a nuke. You get two different factions to play as, the British and the Americans. Playing both is fun, though the British soldiers sound pretty bland, in comparison to real British people :3. It may not go too far in quality because in big scenes or fights the game lags, due to the engine's configurations. The game contains real gun names, though sometimes awkward looks/sounds, and somewhat eccentric reload styles. The graphics in game is not bad, but its definitely not the best for the Nintendo DS system. The game's soundtrack is really good, and can easily pump you up the longer you stay in.
Give it a try!
