Day and night: every match now runs through a full day, with dawn, dusk, a moonlit night and shadows that move with the sun. You can turn it off in Options > Game > Day / night cycle.
Formations: a mixed group sent to one point lines up with tanks in front, infantry behind them and support units at the back, and marches together at the pace of its slowest unit.
Clearer team colours: a coloured apron around every player building, stronger colours on flags and signs, and a coloured disc under every land unit.
Terrain matters: roads, mud, snow, forest and bushes change how fast units move. Infantry in a forest or in bushes is harder to hit, and a little easier to hit on open ground. The selection panel shows the ground under the unit.
Rifles and machine guns can now miss, and experience counts: about 77% of shots hit with no star, up to 97% with three stars.
