This site’s focus is Battlefield 2 but I felt compelled to make a post about the mod Modern Combat (it’s Steam page is here). For a start its made by Black Sand Studio’s who have been involved in many BF2 projects over the years. Modern Combat seems to be inspired by BF2 in many ways, showing what an amazing game the original BF2 is.
The sound is especially note worthy. Weapons sound violent and brutal. The AI is also top notch. Altogether this is a highly recommended mod for the Battlefield Classic fan.
