[4] Unity of Command II is a tactical turn-based wargame which balances between historical accuracy and abstract game design.

[9] Notable gameplay mechanics that were added include fog of war, unit headquarters, supply hubs, airborne ops[10] or the ability to go beyond enemy lines and sabotage their infrastructure.

[12] Rob Zacny, in a review on Vice, noted how the game departed in so many ways from the original, but remained a "simple joy to play", calling it a "wargame that invites a lot of delightful perfectionist revisiting for a long time to come".

[16] Rock, Paper, Shotgun was similarly delighted by the game and its novelties, concluding that "Wargames this canny, attractive, friendly and historically literate come along extremely rarely".

[17] PC Gamer noted in its review that new additions such as specialists and HQ upgrades contribute considerably to the campaign's flexibility, stating that there are also moments of historical divergence in the game.
