D-day is a World War 2 total conversion mod for Red Alert 2, featuring thirteen different countries equipped with over a thousand new units spread across multiple game modes.

10/10 - Agree Disagree

This mod embodies what itd be like if Red Alert 2 and Axis & Allies had a child

It keeps that C&C gameplay but with the setting, units, factions and map styles of a well rounded WW2 RTS. Mind you I am writing this after playing the 3.7b version of the mod.
There is a very nice variety of units to play with and all (so far) seem to be voiced
