- Tile improvements (fortifications, radar towers, coastal cannons), trenches, zone of control, support-unit capture and launch transports, with parabolic barrage arcs drawn between attacker and target. - Focused research that pours points straight into the chosen technology, with per-technology progress kept when the focus changes, plus repeatable levels. - Popularity reworked to integer points, war and pillage effects, minority policies and month-over-month arrows on the nation summary. - City progress bars, square improvement buttons, a technology tab of wide short cards with progress bars, transport cargo readout and double-click to open a city panel.
