Advance Wars is a turn-based strategy game developed by Intelligent Systems and published by Nintendo for the Game Boy Advance. Originally released in 2001, the game puts players in command of a military force across a series of tactical grid-based battles. Players control armies made up of infantry, tanks, aircraft, naval vessels, and artillery, using terrain advantages and unit positioning to outmaneuver and destroy opposing forces. What sets Advance Wars apart from other strategy titles is its commanding officer system, where each CO brings a unique power ability that can shift the tide of battle when activated at the right moment. The colorful cartoon art style contrasts with the deep, layered strategy beneath the surface, making the game approachable for newcomers while offering genuine complexity for players who want to master it. Advance Wars marked a major moment for handheld strategy games and introduced Western audiences to a series that had existed in Japan for years under different names.

Advance Wars offers a full campaign mode that walks players through an extended story involving four nations caught in a continental conflict, with each mission introducing new unit types and tactical challenges. Outside the campaign, players can battle in War Room mode against AI opponents across a selection of standalone maps, or go head to head against a friend using the link cable versus mode. The game includes a Map Editor that lets players design their own battlefields and share them with others locally. Each CO has distinct stat bonuses that affect how their units perform, and learning to match a CO's strengths to a given map is a key part of high-level play. With dozens of missions, a rewarding progression of difficulty, and a surprising amount of content packed into a handheld cartridge, Advance Wars delivers one of the most complete and satisfying strategy experiences available on the Game Boy Advance.
