Difference in the Wii and DS Versions
Wii Version Differences:
First off let me note the game contains all the same weapons and perks from the original COD4. There are a few differences since the wii is a lot weaker than the PS3/360/PC. They lowered the maximum number of players to 10. So there is no ground war mode but there is a new mode called “Squadmate” which was in WAW Wii version. There is now host migration and fully customizable and remap able controls. Players can now hold their guns tilted sideways for smaller one handed guns by twisting the Wii Remote from left to right. The Wii Zapper is compatible with the game. There is no Kill Cam, Wii Motion Plus, or Offline Multiplayer other than Squadmate Mode. The cheats for single player are also different. Ragtime Warfare was replaced with a new “Paintball Gun” cheat, and a Bad Year now requires you to get a headshot, or the enemy will not spawn tires.
DS Version Differences
The DS version of the game allows the player to assume the roles of several anonymous soldiers, who are either affiliated with the British S.A.S. or U.S. Marines. Unlike the console and PC version of Call of Duty 4, players do not directly impact the outcome of the war. Instead of going after the main antagonists of the overall plot (the Four Horsemen: Russian and his allies), the playable characters in the DS version participate in minor missions, such as escaping from an American military base in as it is attacked by enemy forces, or raiding two cargo ships in the stormy black and dark Baltic Sea which may be carrying nuclear materials. The DS version focuses less on the main attempts to end the conflict and more on the supporting role of the various other soldiers who played a part in the war. The player can also be a gunner on a AC 130-Spectre Gunship as are in the regular console/computer version of Call of Duty 4.
