T4M DOWNLOAD LINK:Instructions:To install the engine mod simply go to your steam library, right click Call of Duty WaW, Click properties, Click the Local Files Tab, Then click browse local files. Then drag the .dll into that window that opens.
If you don't have the Steam version of the game your game is probably in C/programfiles(86)/Activition/Call of Duty - World at War

If you have a disk version of Call of Duty WaW then you must download and use a lanfix.exe. A Google search for a Call of Duty WaW lanfix exe will take you to what you need. I personally don't have the disk version of the game but I've seen respected members of this community with disk versions of the game use a lanfix in order to play and they seemed to have no issues. If you have any issues please search the UGX site for details, there are several maps using T4M and this question has been answered quite often.
