Battlefield 2: Unlimited Action is a Battlefield 2 modification which improves upon the base game by fixing many inconsistencies and glitches that were disregarded by EA/DICE, as well as adding new content that is based upon either new ideas, or cut content that never made it to the game's release back in 2005 and the subsequent releases of the three booster/expansion packs. Other goals of this modification are to modernise the game's visuals by adding various new effects, textures and lightmaps; to expand the co-op and singleplayer experience by adding bot support for all map layers, and lastly, to add new and innovative content that will improve upon the general gameplay and appearance of Battlefield 2, while staying true to the game in its vanilla state. - TheObscure
In default Battlefield 2: Euro Force, there were no new maps that featured the 64 player map variants. They only had 16 and 32 player sizes. One of the early goals of my mod is to make sure that all the maps in the game, including the three Euro Force maps, have a 64 player variant as well.
Notable new features of this specific new map variant is the fact that the map is a lot more open with many new vehicles and control points, but the most notable is the addition of helicopters.
