成金大作戦決定版5 is the latest and definitive edition of the Nouveau Riche Operation Series, which has come two and a half years after the release of the previous version. The game involves up to 5 troops fighting against each other in a highly strategic and engaging manner. Each turn, players get to control various units, including infantry, tanks, fighters, bombers, cruisers, battleships, and more, to destroy all enemies and claim their base.

The game is designed to be accessible even to beginners, but the gameplay is challenging enough for experienced players. With the addition of new maps every month, including high-difficulty maps, players can enjoy a new level of gameplay. The game also features new units such as tankettes, cruiser tanks, Apaches, marines, and DD tanks, which add more variety to the game.

One of the most significant changes in the game is the addition of landmines, which are treated as subunits. The game also features invisible stages, where enemy units are not visible, and sea stages with mines and naval units. These improvements make the game more realistic and engaging. The AI has also been enhanced, making the battles more challenging and rewarding.
