Ars writes: "Treyarch's Call of Duty: World at War was criticized out of the gate for attempting to cash in on the success of Call of Duty 4 while stubbornly returning the series to the overdone World War II era. And while the game's co-operative experience and story campaign may be worth playing through, spending a night in the PC version's multiplayer beta has revealed that the title is unlikely to win over fans of the excellent online action of its predecessor.
On paper and even at first blush, the multiplayer of Call of Duty: World at War is almost a play-by-play remake of COD4. The familiar inclusion of ranks and perks are immediately evident, as you begin earning experience through kills and other on-field actions to unlock more weapons and better abilities. The inclusion of kill streak-based rewards is also familiar, though the UAV, airstrike, and helicopter have been replaced with spy planes, artillery, and tanks. The action is fast and furious, melee attacks are ruthlessly efficient, and the basic feeling of COD4 is intact at a low level. "
